This is the equivalent of a microchip from the 1960's NASA Apollo missions. Charlie Duke was CAPCOM for Apollo 11 (only person allowed to talk to Neil Armstrong & Buzz Aldrin) upon descent to the moon.He was a moon walker with Apollo 16. Moon Walker autographs on space used artifacts are extremely rare.
