The 2013 Bicentenary of the Holey Dollar and Dump marked 200 years since the issuance of these unique Australian coins. In 1813, the Holey Dollar was created by cutting a hole in Spanish silver dollars and stamping them with the colony's initials to address a shortage of currency in New South Wales. The leftover silver was used to mint the smaller Dump coin. The bicentenary celebrated these coins' historical significance in Australia's early monetary system and their role in the development of Australian numismatics. Special events and exhibitions highlighted their legacy and continued importance to collectors and historians.
