What Are Space-Flown Gold Dollars?
Space-flown gold dollars refer to special Sacagawea dollar patterns struck in 22-karat gold by the U.S. Mint. Unlike regular circulation coins, these were experimental pieces, known as patterns, and a select few hitched a ride into orbit.
These rare coins feature Sacagawea, the Shoshone guide from the Lewis and Clark expedition, on the obverse, with an eagle on the reverse. What makes them extraordinary is their space travel, adding a layer of numismatic rarity.
The History and Origin of These Rare Coins
Back in 1999, the U.S. Mint struck 39 of these 22-karat gold Sacagawea dollars to promote the upcoming circulation version. Only the top 12 were chosen for flight, with the rest melted down.
They launched aboard Space Shuttle Columbia on mission STS-93 in July 1999, commanded by Eileen Collins—the first woman to lead a shuttle flight. Over five days, they orbited Earth 80 times, covering 1.8 million miles.
This mission highlighted women’s achievements in exploration, tying into Sacagawea’s legacy. The coins returned as space-flown memorabilia, blending numismatics with space history.
Why These Coins Are So Valuable Today
In today’s market, rarity drives value. With just 12 space-flown examples, these gold dollars are ultra-scarce. Their space provenance adds immense appeal to collectors.
Recent auctions show demand surging. They now hold records as the most valuable U.S. gold dollars struck since the Civil War. This relevance stems from growing interest in space memorabilia and numismatic investments.
