Flown Apollo 13 Robbins Medal, approximately 1.25 diameter, with a raised design on the face of the Apollo 13 mission insignia. The reverse of the sterling silver medal is engraved with the full names of astronauts Jim Lovell, Fred Haise, and Jack Swigert, along with spacecraft names Aquarius and Odyssey, the April 11, 1970, launch date, and April 17, 1970, return date. This medal is serial numbered “25.” Medal was in a removable holder on a chain, which will be included. Accompanied by an ALS from Jack Swigert, one page, 7 x 8.75, January 4, 1977. In part: “Apollo 13 was a memorable experience for me. And I hope this Medallion which we carried aboard our spacecraft will bring you the same good fortune Apollo 13 did for me.” Medal is in normal condition, with some scattered wear to the edge from a previous holder. ALS in fine condition, with mild intersecting folds (one passing through a single letter of the signature). Flown Robbins Medals are among the most sought after space collectibles, and this, with a vintage letter of provenance from Swigert—a rarity in itself—is one of the most interesting pairings we have seen.
