Alan Bean’s flown sterling silver tie clip carried into lunar orbit aboard the Command Module Yankee Clipper during the Apollo 12 mission, 1.25 x .75, showing an astronaut with an orange visor carrying the Apollo Lunar Surface Experiments Package (ALSEP). In fine condition. Accompanied by a lengthy handwritten and flight-certified letter of provenance from Bean, in full: “I hereby certify that the accompanying astronaut (I think that it is me) carrying out the Apollo Lunar Surface Experiments Package (ALSEP) now attached to the silver tie bar, was carried aboard our command module, ‘Yankee Clipper,’ during our Apollo 12 mission to the moon. The astronaut carrying ALSEP attached to the silver tie bar has been in my collection since I returned to planet Earth.” An uncommon flown format depicting the premiere instance an Apollo mission placed a complete nuclear-powered ALSEP station on the surface of the moon.
