The 2019 Sacagawea Dollar is a noteworthy piece of U.S. currency, minted at the Denver Mint. This one-dollar coin features a striking design by Glenna Goodacre, with contributions from Emily Damstra. The diameter of the coin measures 26.5 millimeters, and it has a weight of 8.1 grams, adhering to the standard specifications for this type of dollar. Unlike traditional coins, the edge of the Sacagawea Dollar is lettered, adding an interesting tactile element to its design. The material composition consists of 77% copper, 12% zinc, and 1% of other metals over a pure copper core, which gives it durability and a distinctive appearance. Interestingly, this particular coin has a mintage of zero, which could suggest it was not produced for general circulation, making it more desirable to collectors. The lack of mint mark indicates that it was struck without a distinguishing mark from the Denver Mint. Overall, the 2019 Sacagawea Dollar is not only a tribute to Sacagawea's contribution to American history but also a unique collectible coin that embodies both historical significance and modern minting techniques. Its combination of artistry, rarity, and cultural importance make it a fascinating subject for numismatists and collectors alike.
