PSA Grading Metal Coins
When did PSA become experts grading metal coins such as the 1980 Topps Protoype Coins. They are very limited in specimens to be compared to each other for the grades that are given The grades that are listed are for cards not coins I would think they would not grade metal coins minted to be graded the same as baseball cards based on 4 corners and printed on paper stock. I might have missed where they have grades for coins
