Sap Moderator Australia 16876 Posts	Posted 03/07/2022 8:18 pm A surface like this is usually either a sign of acid/corrosive damage, or of corrosion forming underneath the plating on plated steel or plated zinc coins. This coin is solid aluminium-bronze, not plated, so my assumption would be acid damage. A third option would be that it's counterfeit, but a counterfeit would likely be wrong in other ways (size, weight, edge, etc) and seems unlikely given the low face value and collector worth of this coin type. Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis Report this Post to the Staff
