Edge - Electrotype Edge with Joint Where Two Halves are Glued Together617 viewsIf you note that a coin is glued from two parts (obverse and reverse) it is a guarantee it is fake, usually an electrotype. These fakes are often nearly perfect copies - except for the edge. This is an unmasked edge with a clear joint. Often the edge is masked but when observed carefully the joint is still visible.

Edge - Filing746 viewsFiled edge - this is almost a guarantee the coin is fake. Very rarely an ex-jewelry coin has been filed, but there should be other indications that it was once mounted. On some types the edge of the flan was filed before striking, but this is unusual. Occasionally a genuine coin may have a scrape on the edge (maybe the ancient owner rubbed it on a rock?), but this is very rare. Assume a filed edge is fake or consult an expert. Ilya Prokopov

Edge - Cold Pressed Silver463 viewsCold pressed. Very different from a genuine coin edge. Excessive cracking which is rare on genuine coins and usually indicates a fake. There are a few genuine types that typically have many flan cracks, but without an expert opinion, assume such a coin is fake. Ilya Prokopov
