Space Cover 870: Ship vs. Captain's CoverCollectors of recovery ship covers are familiar with covers that have either printed cachets or rubber stamp cachets that were designed by Morris Beck. These covers are not hard-to-find and were produced for MA-8 (Schirra) to the Apollo Soyuz Test Project (ASTP) mission.
In addition to the Beck cacheted covers there are also Captain's covers and ship's cachet covers for many of the crewed missions. These covers were produced by the prime recovery ship in limited numbers primarily for the crew. But is there a 'black and white' definition of what is considered a Captain's cover and what is considered a ship's cover? Are any cover's signed by the Commanding Officer considered a Captain's cover or are any covers printed specially for the use of the crew considered ship's covers?
The first cover that I am aware of that that's considered a Captain's cover was for the MA-6 (Glenn) Mercury mission from the USS Randolph, the prime recovery ship for MA-6 (See photo above). This cover had a sticker cachet that was applied to the cover and are available both signed and unsigned by the Captain of the USS Randolph (Max Berns, Jr.). Since the cachet was used exclusively by the ship with some covers signed by the Commanding Officer is it a Captain's cover or a ship's cover?
The next Mercury mission, MA-7, was recovered by the USS Intrepid and also had a printed cachet specifically for the USS Intrepid. Like the USS Randolph cover it is also available signed and unsigned by the Commanding Officer of the USS Intrepid (James Abbot Jr.). Again, is this considered a Captain's cover or is it a ship's cover?

Note that there is a USS Decatur cover for the recovery of the unmanned MA-4 spacecraft but I believe this is considered a ship's cachet cover and not a Captain's cover (See photo below). This cover has a typed name of LT. J.A. Felt above the return address of the USS Decatur and not Commander Royal Thomas Daniel Jr. who was the Commanding Officer.

There is also a cover from the USS Lake Champlain for the recovery of Alan Shepard during the MR-3 mission that has a printed cachet and the ship's return address. Some collector's may consider it to be a Captain's cover and some a ship's cover? Which is it?
The first Captain's cover for the Gemini program was for the recovery of Jim McDivitt and Edward White II by the USS Wasp during the Gemini 4 mission (See Photo below). This was a printed cover with a printed signature of the Commanding Officer (James W. Conger). This cover as always been described as a Captain's cover, so there doesn't appear to be any debate as to whether it is a Captain's cover or a ship's cover. But what specifically makes it a Captain's cover? Did Captain Conger have these covers made for the crew?

There were other Captain's covers to commemorate the recovery of Gemini missions 6, 7, 9, 11 and 12 (See photo below for Gemini 9). I'm not aware of Captain's covers for Gemini's 3, 5, 8, and 10.

The most difficult ship's cover of the Gemini program is the one for Gemini 10. After many years of looking I was finally able to add one to my collection earlier this year (See photo below).

There were Captain's covers for the Apollo program as well. The first one that I'm aware of is the one for Apollo 11. There are also Captain's covers for Apollos 12, 14, 15, 16 and 17. I don't recall seeing a Captain's cover for Apollos 7, 8, 9, 10 and 13, although there is a ships cover for Apollo 10. The Apollo 10 ship's cover is the most difficult to find. Below is a photo of the Apollo 14 Captain's cover

There is also a cover with a Beck Rubber Stamp cachet for Apollo 9 with a printed LM in the lower right-hand corner. I don't believe this is either a Captain's cover or a ship's cover, so who made this cover?

There are also Captain's covers for Skylabs II, III and IV and a cover for ASTP that was privately made but was on the USS New Orleans for the recovery of the ASTP astronauts (See Photo Below). I've seen it described as a Captain's cover or a 'Crew's cover' but to my knowledge although covers were given to the crew it wasn't 'officially' made at the direction of or signed by the Captain (I believe these covers were produced by space cover collector Dr. Ben Ramkisson who was on the USS New Orleans).
Note that it is cancelled on July 25, 1975, the day after the ASTP splashdown. The reason for this is that this cover was on-board the USS New Orleans and the ship's postoffice was closed on July 24, 1975, the day the ASTP crew was recovered. Therefore it was cancelled the next day that the ship's postoffice was open, which was July 25, 1975.

If any collectSPACE member has additional information regarding Captain's covers please post it. Also if there are Captain's covers for Geminis 3, 5, 8, 10 and 11 and Apollos 7, 8, 9, 10 and 13 please post them.
