California gold coinage
California gold coinage is a broad category of privately-issued coin-like items that were used in place of official currency in the United States territory (later state) of California during the gold rush of 1849. Since the federal government reserves the right to issue legal tender coins, California gold coinage is a misnomer and actually references coin-like ingots with a stated tender value, tokens with a stated tender value (denominated), and tokens without a stated tender value (non-denominated).
