This month, in celebration of World Space Week, the U.S. Mint is going where no coin has gone before. Outer space! Well, actually, a lot of coins have been there before. In fact, coins from the United States Mint have journeyed across the galaxy and witnessed historic moments in space exploration.
The first U.S. coin officially left Earth’s atmosphere in 1999—the Sacagawea Golden Dollar (which was re-released this year as a special Anniversary Gold Proof Coin). In the 26 years since, other coins have made the trip into space, traveling to Mars, the International Space Station (ISS), and the Kuiper Belt.
Maryland and Florida state quarters are aboard NASA’s New Horizons spacecraft to honor the states that designed and launched the craft. The two quarters, which began their journey in 2006, serve as spin balance weights. They helped make history in January 2019 when New Horizons flew past Ultima Thule in the Kuiper Belt, the furthest object ever explored.
Also in 2019, two Apollo 11 50th Anniversary Commemorative Coins were on board the ISS. Astronaut Christina Koch sent a message from the space station before the coins returned to Earth.
In addition to sending coins to space, the Mint also designs coins and medals to honor the accomplishments of the U.S. space program, the latest of which are the American Innovation $1 coins for Florida and Texas.
