A neat example of a copper/silver ‘half-breed’, consisting of silver and copper intergrown. This is a classic for Michigan copper country, and this is a neat example with a peculiar mining artifact – what appears to be an indent from a rock hammer right in the middle of the specimen! A great conversation piece.
