Flight-flown sterling silver Fliteline medallion carried aboard the Gemini 5 mission. Medallion measures one inch in diameter, with a raised mission insignia on one side, including the slogan “8 Days or Bust,” and the crew’s name, and engraved on the reverse, “August 21-29, 1965.” This medal was presented to NASA’s Physical Conditioning Supervisor, Joe Garino, Jr., by Gordon Cooper. In fine condition, with expected light wear and some scattered light pitting to date side of medallion. Accompanied by a certificate of authenticity from Garino stating he was presented the medallion by Cooper and that “the medallion pictures a Conestoga wagon with the motto ‘8 Days or Bust,’ removed by NASA from the Gemini 5 astronauts; spacesuits’ but carried by Cooper on patches and medallions on the flight.” NASA managers objected to the slogan as they felt it placed too much emphasis on the mission length and not the experiments.
