20hhgd.t ((COPPER CORE)), $5 MINIMUM BID, Attributed to Michigan, 3 x 3 x 3 cm, Miniature | |
Here is a Copper core sample with one end polished somewhat and coated with an epoxy cap. I am wondering about this and the possibility that this was a large slab of copper rich specimen that was slabbed and then these cores taken from the slab rather than being part of a mining operation. ex Glenn Davidson collection. |
