Abstract

Arsenic-copper alloys are not common after the Early Bronze Age. The discovery of a group of 3rd century BC coins, probably from Tunisia, with surface metal composition of up to 29% arsenic in the copper prompted this metallurgical examination. The arsenic was found to occur in greatest concentration on the coin surfaces as the result of inverse segregation during casting.
