Ingots
U.S. Mint San Francisco, 1959 Round Dated Hallmark, #1683, Lot #38, 999.75 Fine. 21.05 ozs.
The 25-ounce ingots were one of the default sizes produced by the Mint, along with 5-ounce and 100-ounce sizes. This original ingot was thoughtfully laid out - the hallmark was positioned just left of a circular casting flaw on the upper portion of the top side. Medium gray toning throughout.
