One Dollar Bill, Apollo 8

This United States one dollar bill is a memento of Apollo 8, the second human flight and the first human lunar orbital flight of the Apollo program in December 1968. As part of the official process of certifying the flight, before human spaceflights, the National Aeronautic Association (NAA) had the astronauts or others autograph dollar bills, witnessed by the NAA official for the flight (who sometimes also signed the bill). The bills were then placed aboard the spacecraft. After the mission, recovering the identifiable bills served "as the basis for certification of the identity of the astronauts on each of the flights." James Lovell, Frank Borman, and Bill Anders signed the reverse of this bill.

In consultation with the NAA, the NASA Johnson Space Center transferred this bill to the National Air and Space Museum in 1976.
