Dave Scott’s gold-plated Fliteline medallion flown aboard the Gemini 8 mission, approximately 1″ in diameter, with a raised insignia of the mission on the front, and the reverse engraved, “First to dock in space. 16, March, 1966,” and encircled by the names of the crew members. Medallion has been professionally cleaned and condition is mint state. Accompanied by a signed letter of authenticity from Scott, in part: “I hereby certify that the gold-plated Gemini VIII medallion included with this letter was flown aboard the Gemini VIII mission…This medallion has been in my personal collection since we returned from the mission.” After completing the world's first orbital docking, the Gemini VIII capsule, still docked to the Agena, began to roll. The crew undocked from the Agena and determined the problem to be a stuck thruster on the spacecraft, which now tumbled at the dizzying rate of one revolution per second. Armstrong and Scott used the capsule's reentry control thrusters to stop the motion, an emergency decision that truncated their mission just ten hours after launch.
