The Lesher dollar is a type of collectible coin produced in 1985 by the California artist and coin designer, William R. "Bill" Lesher. It was created as a privately issued silver dollar coin, commemorating the state of California's mining heritage and designed to serve as a local currency in the vicinity of the town of Kettleman City. Its distinctive features include intricate engravings and the use of specific silver content, making it a coveted item among collectors interested in modern numismatics and alternative currency. The Lesher dollar differs from officially minted coins by the U.S. government, emphasizing its status as a token rather than a legal tender coin.
