Florins

 The Australian Florin was a coin used in the Commonwealth of Australia before 1966 when decimalisation occurred. These coins were first minted in 1910 to the same size specifications as the florin produced in the United Kingdom. The last year Florins were produced was 1963. 

Florins minted from 1910 to 1945 have a silver purity of 92.5% and as such as 0.3363 of a troy ounce of Silver. Florins produced from 1946 onwards have a 50% silver content and as such a silver weight of 0.1818 troy ounces.
