This 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.
