In what ranks among one of the most unique numismatic auctions in recent memory, Stack’s Bowers Galleries closed the sale of eight rare Sacagawea dollars — seven struck in 22-karat gold that were flown aboard Space Shuttle Columbia, plus the first-struck 2025-W Sacagawea in 24-karat gold — on behalf of the United States Mint.
Bids for the 22-karat pieces ranged from $360,001 to $550,001, while the 24-karat anniversary coin realized $120,001.
Originally, 39 Sacagawea dollars were struck in 22-karat gold, but only 12 of the finest were selected to fly aboard Columbia in July 1999; the rest were destroyed. Commanded by Col. Eileen Collins, the mission marked the first shuttle flight led by a woman. During their 1.8 million-mile journey — about 80 Earth orbits — these proofs promoted awareness of the Sacagawea dollar, which entered circulation the following year.
All seven were certified by Professional Coin Grading Service (PCGS) as Proof-69 Deep Cameo.
