2018-P American Innovation Dollar

To introduce the new series in 2018—before the States and territories are honored—a special American Innovation $1 Coin was minted and issued. The coin pays homage to President George Washington who issued the first U.S. patent to Samuel Hopkins on July 31, 1790, for developing a process for making potash, an ingredient found in fertilizer. Millions of patents have been issued since then, a testament to our nation’s entrepreneurial spirit, and the remarkable innovation and discovery it unleashes.
