In the weeks before Apollo 11 launched, Neil Armstrong, Buzz Aldrin and Michael Collins spent part of their quarantine signing hundreds of autographs, not for fans, but so their families could sell them if the mission killed them, since no insurer would cover astronauts at all. The Apollo 1 fire in January 1967 had killed all three of its crew during a launch rehearsal, a fact none of the Apollo 11 astronauts needed reminding of. Crews on Apollo 12 through 16 signed their own insurance covers during quarantine, and every one of those missions also returned its crew alive. Individual Apollo 11 covers have sold at auction for anywhere from around $8,000 to well over $13,000 depending on type and condition, with a full set spanning several Apollo missions fetching $16,500 at one sale. There were, it turns out, three distinct designs among the Apollo 11 covers alone, cataloged by collectors as Types 1 through 3, with the rarest commanding the highest prices decades later.
