1918-M Pattern (0.500 Silver) One Shilling

The 1918-M Pattern Shilling is an exceptionally rare 50% silver type issued by the Melbourne Mint. The total number of pieces created is unknown however two pieces are currently know to exist. The obverse features an effigy of George V just as one would find on the standard 1918 Shilling. The reverse is also mostly typical however it has been slightly modified to include two large dots on either side of the arrows that point toward the dates (see image below).

The high prices of silver at the conclusion of the First World War led Australia to consider altering the metal compositions of its silver pieces. The British had already abandoned their sterling standard and had adopted an alloy of 50% silver and 50% copper. (John Sharples, 1985) This pattern appears to be one of the early experiments with a similar alloy for Australia. Despite the initial intention the change was not implemented.
