Holey Dollar and Dump

Holey dollar is the name given to coins used in the early history of two British settlements: Prince Edward Island (now part of Canada) and New South Wales. The middle was punched out of Spanish Dollar, creating two parts: a small coin, known as a "dump" in Australia, and a "holey dollar". This coin was one of the first coins struck in Australia

The Holey Dollar and Dump are the only Australian coins which have had their ‘legal tender’ status removed, or been ‘demonetised’.
