Comment

Type: M11 / R13

This perversely unknown type caused a sensation when it was discovered during a stocktake at the Science Museum of Victoria in the 1970s. The two known examples are believed to be from the former property of H.M. Le Souef, the late Deputy Master of the Melbourne Mint who left much of his collection to the museum.

Dies prepared by the Royal Mint, London

Between 1919 and 1921 a series of experiments were undertaken for a square coinage in nickel to replace the large bronze penny and halfpenny coins.

Interesting fact

The Kookaburra Pattern 1 Penny coin from 1921 features a unique design of a kookaburra bird on the reverse side, which was created by artist Edgar Bertram Mackennal. The coin was minted in a small quantity, with only 10,000 coins produced, making it a rare and highly sought-after collector's item.
