2009 $1 1852 Adelaide Assay Office Gold Ingot Selectively Gold Plated Silver Proof Coin

This coin recreates the design of one of the gold ingots produced by the Adelaide Assay Office to overcome the financial crisis in the Colony of South Australia. These ingots were only produced between March and November 1852 and were the first, gold legal tender medium of exchange in Australia. Prized by collectors, few originals exist today.
