Apollo 15 was the fourth manned mission to land on the Moon. It was the first to use the Lunar Rover, which allowed the astronauts the ability to journey over extended distances from their lunar module.

The crew consisted of commander David R. Scott, lunar module pilot James B. Irwin, and command module pilot Alfred M. Worden.

Sieger crew-owned Apollo 15 flown cover

One of the 300 Sieger Crew-Owned Covers

The Story

Realizing there may be a market for space flown philatelic items, Herman E. Sieger of Lorch, Germany, a major European stamp dealer, set out in 1970 to recruit an Apollo crew to carry a small number of postmarked envelopes - called "covers" by collectors - to the moon.

In pursuit of his idea, Sieger approached H. Walter Eiermann, a naturalized American citizen, who had been privately employed for many years in the Cape Kennedy area and was well acquainted with many in the astronaut corps. Sieger became acquainted with H. Walter Eiermann while on a visit to Cape Kennedy in 1970.

Eiermann, working on Sieger's behalf, was able to interest the crew of Apollo 15.

In the spring of 1971, during the Apollo 15 crew-training period at Cape Kennedy, Eiermann proposed to Scott, and later to Worden and Irwin, that the astronauts carry 100 special covers to the lunar surface for him. It is the contention of the astronauts that there was to be no commercialization or advertising of these covers and that nothing would be done with them until after completion of the Apollo program. In return, Eiermann offered a monetary consideration, approximately $7,000 apiece, in the form of savings accounts in a German bank. The astronauts agreed and also decided to carry 300 similar covers for themselves, 100 for each, but two were destroyed before the flight, making a total of 398 that were flown.

Due to weight constraints, NASA required that all the items carried aboard the Apollo spacecraft be manifested. Although the Apollo 15 crew was later to claim an innocent oversight, the covers, which were carried in Scott's spacesuit pocket, were not recorded pre-flight.

It is important to note that the Personal Preference Kits (PPKs) for the Apollo 15 crewmembers were packed and stored aboard the spacecraft days before their launch to the moon, so these covers could not have been packed if they were to have a launch day post office cancellation. The 400 covers were hand delivered to the post office (HQS Bldg.) at Kennedy Space Center just after midnight the morning of the launch. The mission launched at 1:34 pm that afternoon. There was a postal employee working late there and had the covers machine cancelled, as requested from the astronaut support office, even though the liftoff of Apollo 15 was planned for 9+ hours away. Once the special cachet envelopes were processed in less than 15 minutes or so, the batch of covers were brought to a nearby facility, the Manned Spacecraft Operations Building (also known as the Operations and Checkout Facility), where the batch of covers were vacuum packed so that the bundle was not thicker than 5 cm. Next, they were sealed in fireproof Teflon-coated fiberglass, and delivered to Launch Complex 39A's White Room after Scott and his crewmates had arrived at the pad for their final launch preparations and spacecraft entry. While there, Scott received the special package and put the small bundle into one of his leg-pockets of the spacesuit he had on.

After splashdown, aboard the USS Okinawa, the Apollo 15 recovery ship, the astronauts purchased twin eight-cent stamps and affixed them to these covers. The covers were then canceled and date-stamped August 7, 1971, their landing date, in the shipboard post office. The astronauts later autographed these covers while flying from Hawaii to Houston on Aug. 31, 1971.

100 of these covers carried the handwritten notation, "Landed at Hadley moon July 30, 1971. Dave Scott, Jim Irwin", and the additional legend - "This is to certify that this cover was onboard the Falcon at the Hadley Apennine, Moon, July 30-August 2, 1971" typed on their backs and signed by a notary public. It was these covers that later came on to the commercial philately market in Europe.

On September 2, 1971, Scott mailed the 100 specially certified covers to Eiermann, who at that time was in Stuttgart, Germany. Eiermann delivered these covers to Sieger. Sieger paid Eiermann an unspecified sum for the covers and then advertised them for sale. By November 1971, ninety-nine of them had been sold at an average price of $1,500 each.

When the news of the sale reached the United States, Scott telephoned Eiermann to request that sales be stopped and the covers returned but he was unsuccessful. In February 1972, in an effort to save their careers and reputations, the astronauts decided not to accept the money and Scott took steps to assure that the funds were returned to Eiermann. Eiermann suggested, as an alternative to the savings accounts, that each astronaut receive a commemorative stamp album for their families. This suggestion, initially accepted by the astronauts, was rejected in April 1972 after further consideration and the astronauts returned the $7000 they had each received. However a Congressional investigation wanted to make an example of the Astronauts and so NASA had no choice but to suspend them from active flight status. NASA also confiscated the 298 covers. It is unfortunate because there might never have been a problem if Sieger had honored the agreement not to offer the covers for sale until the Apollo program was completed.

To prevent similar incidents from occurring again, NASA drafted rules as to what astronauts would be allowed to take with them into space. Future crewmembers would be bound not to publicize the contents of their "Personal Preference Kit" (PPKs) until they retired from the corps. The astronauts were also required to sign an agreement restricting transfer of their flown memorabilia to gifts and donations - sale of memorabilia was strictly prohibited.

In 1983, eleven years later, the U.S. Postal Service announced plans to fly 260,000 covers aboard the space shuttle. Al Worden, seeing the similarities between his confiscated covers and those set to fly on STS-8, sued the government for the return of his crew's 298 covers. In an out-of-court settlement, the covers were returned to the crew. Upon their receipt, the entire crew drafted, signed and had notarized a letter of provenance for each cover, which today has become an integral part of their lore.


The 398 unauthorized covers (initially 400 but two destroyed) are lightweight onion skin envelopes carrying as a cachet, a replica of the official Apollo 15 patch overprinted with an Air Force wing and propeller emblem. They were part of a large order of covers paid for by a privately employed public relations man with a wide circle of friends among the NASA astronauts.

The 398 covers were properly packaged for flight and carried on board Apollo 15 by Scott in a pocket of his space suit; each having been canceled at the Kennedy Space Center Post Office early on July 26, 1971, the morning of the flight.

There are differences in appearance between Sieger's 100 covers and the 298 Sieger/Crew Owned covers, including different combinations of stamps that were affixed.

Apollo 15 flown Sieger cover

The 100 Sieger covers have a handwritten inscription on their front upper left corner stating:

JULY 30 1971
(signed Dave Scott & Jim Irwin)

On the reverse is a typed and notarized inscription that reads:

This is to certify that this cover was onboard the Falcon at the Hadley-Apennine, Moon, July 30-August 2, 1971

Notary stamped and signed Mrs. C. B. Carsey. Her notary raised seal is also applied to the cover.

Also on the reverse, in the lower left reverse corner, Sieger's name "H.W. Sieger" is stamped then signed by him below a handwritten serial number.

Apollo 15 flown Sieger crew-owned cover

In comparison, the 298 Sieger/Crew Owned covers have the following inscription printed on their front upper left corner:

#____ OF 300 TO THE

Although images of all 298 Sieger/Crew Owned have not been reviewed, it seems that the handwritten correction in the upper left corner, changing 300 to 400, stopped somewhere between 69 and 100. We will have to monitor this as other covers come to market.

All the covers are also autographed by the crew on the front lower left corner.

Sieger cover insert

Some of the Sieger/Crew Owned covers have a small (unflown) card inserted inside the cover, some signed by a crewmember, that reads:

This cover is #____ of 300 postmarked just prior to the launch of Apollo 15 on July 26, 1971 at Kennedy Space Center; stowed aboard the spacecraft in a sealed fireproof packet; carried to the lunar surface in LM "FALCON"; returned to earth in CM "ENDEAVOUR"; and postmarked immediately after splashdown on August 7, 1971 by the U. S. Navy Postal Station aboard the recovery ship USS OKINAWA.

Finally, in the upper right corner of the reverse of the Sieger/Crew Owned covers, not the Sieger 100 covers, is the small handwritten initials of S. Neil Hosenball (SNH), NASA's general counsel, and a serial number, which NASA assigned at the time of their confiscation. The Sieger/Crew Owned covers are numbered 1-298 and the 60 impounded Phases of the Moon covers taken from Worden are numbered 299-358.

Stamp combinations used on Apollo 15 flown Sieger covers

Shown above are three different stamp combinations for the flown Apollo 15 Sieger / Crew-Owned covers

A Hierarchy of Desirability

As these treasured Covers have trickled onto the market over the last 30 years, collectors have had the opportunity to closely examine their nuances. In doing so, many collectors have determined a hierarchy of desirability. In other words, if given a choice, which Covers would be considered the most desirable. Basically, the Covers seem identical, but here are some considerations:

  1. Look closely at the twin "Decade of Achievement" stamps at the lower right of each cover. Although the twin stamps are separate stamps depicting separate images, put together they show one complete contiguous image. The left image is of the Earth and LM in the background and the right image shows Scott and Irwin in the Lover rover. When properly positioned the lunar surface as well as the trail in Space align together, and there is no gap between the two images. So imagine the astronauts aboard the recovery ship affixing stamps. They just wanted to complete the task of getting the stamps put on the Covers and not really considering the configuration. Look at the images shown above. The right and left Covers depict the proper and most desirable stamp configuration. The center Cover shows the stamps in the wrong order. And there are also examples where the individual stamps were affixed (not attached together) in both the incorrect and correct order.
  2. Then there is the issue of the single stamp in the top right corner. It seems that the Earthrise and the First Man stamps top the list of popularity. The Antarctic Treaty stamp, having nothing to do with Space or the Moon is least desirable. Some feel that the Earthrise is most desirable, not just because of the iconic image, but also due to the extra two Jefferson 1 cent stamps that had to also be affixed to complete the required postage, which required yet more effort on the part of the crew.
  3. Next is the serial number consideration. Low serial numbers are always considered most desirable by collectors no matter what the collectible is. Covers numbered 99 or less (2 digits) would be considered most desirable. Also, as noted above, the first covers certified by the crew also had the handwritten correction in the upper left that changed the number to 400 from the printed 300. The highest number with handwritten correction found thus far is 94., so we will speculate that Covers numbered 100 and under have the handwritten correction.
  4. The card insert. Although unflown, many of the covers have this insert inside the Cover that again displays the serial number. A very few of them are also signed by a crew member. A signed insert card would be most desirable, however the fact that it was not flown and not seen within the Cover, these remain least important.

Collector Commentary and Observations

In the final analysis of what makes a rarity desirable and in high demand and valuable, it is some combination of the story, the circumstances and the "sizzle" It is not always about numbers or scarcity. In creating the hierarchy of flown covers, the 214 Flown Apollo 11 Covers have always been the most sought after because of the fact that they accompanied the first men to land on the Moon. And, due no less in part to man's fascination with scandal and controversy, these Flown Apollo 15 Sieger Covers have to come in second as the story line reads like a movie script. One also has to consider that the effort put forth by the crew to make these covers what they were was unprecedented, with the post office cancellations, the affixing of the stamps, the certifications; both on the covers and the later notarized letters. Considering that most astronauts today will comment that the only thing on their minds during training was to get home alive and that they paid very little attention to the unimportant stuff, like how many of this or that was on board the spacecraft, it seems notable how much effort was expended. What a story!

Other covers flown on Apollo 15

For the record, in addition to the 398 Apollo 15 Sieger and Sieger/Crew Owned Flown covers, the following covers, which were properly authorized and manifested, were carried aboard the command module and flew in lunar orbit:

  • Apollo 15 flown Wright brothers cover
    1 Wright Brothers commemorative cover dated 1928 and autographed by Orville Wright (shown on the right), which was carried by Worden for a friend. The cover was sold at auction in 2007 (see annex E).
  • Apollo 15 flown Baker cover
    1 cover labeled "flown to the Moon" bearing a First Man on the Moon stamp and a Bliss Centennial three-cent stamp, which was carried by Irwin for a personal friend of Apollo 12 astronaut Richard Gordon.

    Addendum by Chris Spain (2015): The cover is now illustrated on the right, and seems to have been carried by Scott rather than Irwin. A stuffer (apparently unflown) was included with the cover on which Scott again identified the envelope as having been flown on the mission for the recipient.

  • Apollo 15 flown Shamrock cover

    Apollo 15 flown Shamrock cover alternative design

    8 covers (now referred to as the Shamrock Covers) imprinted with a green shamrock, a small Apollo 15 emblem and a rendering of the Lunar Rover with two astronauts, bearing the notation, "Carried to the moon - Jim Irwin," which were carried by Irwin. Each is numbered (1 through 8) within a circle in the lower left front corner . Apollo 15 was the first mission to utilize the Lunar Rover. Irwin was of Irish decent and he held an affection for that, which is why he carried these particular covers. (see annex D).

    Addendum by Chris Spain (2019): According to evidence submitted to the hearing into the Apollo 15 stamp scandal[1] one of Irwin's 8 Shamrock covers was given to Forrest J. Rhodes, who ran the postal facility at KSC, and one to Ray Burton, the president of the Kennedy Space Center Philatelic Society.

    One of these two covers is shown on the right, and unlike the Shamrock cover shown above, it is inscribed by Irwin "This envelope flown to the moon on Apollo 15", and has two 8c Decade of Achievement stamps affixed along with a Sep 29, 1971 KSC cancelation (apparently the day Irwin visited the KSC to gift the covers).

    Irwin retained the other 6 covers and it seems that these have the appearance of the Shamrock cover shown at upper right - with no stamps affixed, and likely numbered 1 through 6 by Irwin at a later date.

    Addendum by Howard C. Weinberger (2020): In the 1970's, a professional golfer named Jim Lawler, of Irish decent, befriended Jim Irwin and helped him and Mrs. Irwin with a few things. In appreciation, they gifted him one of the Shamrock Covers. The serial number of this cover is not known.

  • Apollo 15 flown phases of the moon cover

    One of the flown "Phases of the Moon" covers

    144 Apollo 15 covers that were created by German stamp dealer F. Herrick were carried by CMP Al Worden in his command module PPK. All of the 144 covers were affixed with a special printed cachet sticker showing 15 phases of the moon.

    Naturally, the covers have gone on to be known as the Phases of the Moon covers. It has been erroneously reported in earlier writings that only 100 of the 144 were affixed with the Phases of the Moon sticker, but Al Worden is emphatic that all of them were Phases of the Moon covers.

    On the USS Okinawa, the Apollo 15 recovery ship, the astronauts affixed two eight-cent Decade of Achievement stamps and one U.S. Mail eight-cent stamp, which were purchased on board by Worden, on each of the covers and then had the covers canceled with the recovery date by the shipboard post office. The astronauts later autographed these covers while flying back from Hawaii to Houston. There are no Phases of the Moon covers with a KSC launch date cancellation and any such covers are suspicious and should not be considered genuine. The only post office cancellation is the August 7, 1971 USS Okinawa cancellation.

    Worden sent all 144 covers to Herrick for finalizing and safekeeping after his return.

    Herrick and his son stamped the covers, after the mission, with the launch and recovery dates. The launch and recovery stamps are not official post office cancellations but rubber stamps created by Herrick. There were at least two variations of the launch stamp, one oval and one circular, and just one variation of the recovery stamp, which was circular. Herrick was not consistent with the application of these stamps. Some covers have the launch stamp on the front and the recovery stamp on the reverse while others have both stamps on the reverse. Other combinations are possible. Some stamps are in red ink while others are in black.

    When word came of the NASA investigation into the carrying of the covers, Worden instructed Herrick to return them all to him. According to Herrick he personally sold three of his covers, had sent several to Europe for eventual sale, and had sold ten more through a dealer on commission. It was Herrick who also claimed that 16 of the covers were torn or damaged and were destroyed, but only he could confirm that as Worden had not been witness to that. In the end, Herrick only returned 60 of the 144 covers to Worden, which were then impounded by NASA. Years later, after their release back to Worden, he sold most of them to pay off the remaining debts he amassed during his 1982 U.S. Congressional run.

    Only the 60 covers that were returned to Worden, of the 144 originals, were impounded by NASA. NASA was unable to get hold of the 84 that Herrick might have had or sold, which means that only Worden's 60 impounded covers have the desirable serial number and initials of S. Neil Hosenball (SNH), NASA's general counsel, under the flap on the reverse. The numbering sequence for the Phases of the Moon covers ran from 299 - 358, leaving off from numbers 1 - 298 assigned to the Sieger Crew Owned covers. Furthermore, only these 60 covers also have the accompanying notarized letter that is signed by the entire crew which explains the story of the covers. The letter is similar to the notarized Sieger/Crew Owned cover letter. It differs in that it states that these were flown in lunar orbit and not to the surface as the Sieger/Crew Owned covers did. The letter incorrectly states that the covers were post office canceled on the day of launch, which they were not. There are a few covers which exist that also are accompanied by a separate Al Worden letter that corrects this fact. Obviously, the most desirable would be one of the 60 Worden covers with both letters .

    To date, no information has been developed indicating that there were agreements or arrangements between Herrick and Worden whereby Worden was to have received anything of value from any sale of the covers by Herrick.

  • 2 U.S. Postal Service covers, one of which was publicly canceled on the Moon by Scott at the request of the U.S. Postal Service; the second cover, a backup, was not taken to the lunar surface. Both covers have been returned to the Postal Service (in Washington, D. C.)
  • 87 Apollo 12 covers (initially thought to be 88) that did not fly on that mission and which were carried on Apollo 15 by Irwin for Barbara Gordon, wife of Apollo 12 astronaut Richard Gordon. These are detailed on the main Apollo Flown Covers page.

[1] Wikipedia references a letter from James C. Fletcher to Clinton P. Anderson (Aug 2, 1972) as indicating that "One of Irwin's covers from the group of eight, with a shamrock design as its cachet, was given to Rhodes and one to the president of the Kennedy Space Center Philatelic Society; Irwin said in 1972 that he had retained the other six."
