What if the loose change in your pocket once circled Earth at thousands of miles per hour? That’s exactly what happened with a set of space-flown Sacagawea dollar coins — and collectors just proved how valuable that cosmic journey was when they sold for over $500,000 at auction. But the real story behind these coins is even more fascinating.
What Are Space-Flown Sacagawea Dollars?
The U.S. Mint first introduced the Sacagawea dollar coin in 2000, featuring the Shoshone woman who guided Lewis and Clark. But a handful of these coins went beyond everyday circulation — they were launched aboard the Space Shuttle Columbia (STS-93) in 1999. Traveling beyond Earth turned them from pocket change into priceless artifacts.
The History Behind These Rare Coins
Before they were auction stars, these coins had an unusual journey. NASA carried 39 Sacagawea dollars into orbit as part of a partnership with the U.S. Mint to celebrate space exploration and American history. After the mission, the coins were returned, documented, and later preserved. Their connection to both space history and numismatics makes them a double rarity.

The appeal lies in the mix of American heritage, astronaut history, and numismatic rarity.
