Threepence (Australian coin)

The Australian threepence (pron. "thruppence"), commonly referred to as the "threepenny bit", is a small silver coin used in the Commonwealth of Australia prior to decimalisation. It was minted from 1910 until 1964, excluding 1913, 1929–1933 inclusive, 1937, 1945 and 1946. After decimalisation on 14 February 1966, the coin was equivalent to ⁠2+1/2⁠c, but was rapidly withdrawn from circulation.

During World War II, threepence production was supplemented by coinage produced by the United States Mint at the San Francisco and Denver mints. Coins minted at the San Francisco mint from 1942 to 1944 contain a small capital S on the reverse, while coins produced at the Denver mint from 1942 to 1943 have a small capital D on the reverse.
