A-Mark Precious Metals’ Stack’s Bowers Galleries auctions Sacagawea gold dollars

A-Mark Precious Metals (AMRK) announced that its Stack’s Bowers Galleries subsidiary auctioned seven year 2000 Sacagawea 22 karat gold dollars owned by the United States Mint in a live auction held in their Costa Mesa, California, studios on September 12, 2025. The coins honor the pioneering spirit of American women. Sacagawea helped Lewis and Clark explore the Louisiana Territory and traveled with the expedition to the Pacific Ocean while establishing important cultural contacts and an understanding of the natural environment. In July 1999 the Space Shuttle Columbia, under the command of USAF Col. Eileen Collins, the first woman to command a Space Shuttle Mission, took 12 gold Sacagawea coins into orbit, where they traveled nearly two million miles. Col. Collins earned the Distinguished Flying Cross for the mission. The coins feature a “W” mintmark for the United States Mint’s West Point, New York, facility and since returning from space were stored primarily at the Fort Knox Bullion Depository in Kentucky. The United States Mint has confirmed that the other five of the 12 space-flown coins will be placed into their heritage collection and other public institutions, permanently out of reach for collectors.
