Alan Bean’s sterling silver tie clip flown to the lunar surface aboard the Apollo 12 LM Intrepid, 1.25 x .75, showing an astronaut with an orange visor carrying the Apollo Lunar Surface Experiments Package (ALSEP). In fine condition. From the personal collection of Alan Bean. 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 landed on the moon in our lunar module ‘Intrepid.’ It remained on the moon for 33 hours and then launched with Pete Conrad and me to join Dick Gordon in our orbiting command module, ‘Yankee Clipper,’ for our return to Earth. This pin has been in my personal collection since that time in November 1969.” An uncommon and appealing lunar-flown tie clip depicting the premiere instance an Apollo mission placed a complete nuclear-powered ALSEP station on the surface of the moon.
