1/2 Penny - Crocker and Hamilton Adelaide, Port Adelaide, Burra Burra

Crocker and Hamilton operated as merchants in South Australia during the copper boom of the 1850s, a period when the Burra Burra mine — then one of the richest copper deposits in the world — was driving extraordinary commercial expansion across the colony. Colonial-era South Australian tradesmen's tokens like this one emerged because the official copper coinage supply from Britain was chronically insufficient to meet the demands of a rapidly monetising frontier economy. Private traders filled the gap, issuing tokens that circulated freely and were broadly accepted.

The Adelaide, Port Adelaide, and Burra Burra legends place this token explicitly within that copper-trade corridor.
