coins how to tell apart a sterling silver proof crown to a cupro nickel?
I bought a coin of ebay it said it was a sterling silver proof crown, but i think is cupro nickel is the any way to tell the difference without a COA
It seems that it is not easy for the catalogs say the weights are the same. Since you live in the UK see a local dealer. I don't think anyone can really help you here, hope a UK collector can.
