I just bought some older bullion grade ASEs the other day and there was one that jumped out at me and made me consider that it might be fake. It was a 1988 (all the rest were 1994 and newer) which seemed to have a different luster to it, a bit more dished in the fields, and the area of the flag where the stars are is less detailed than the others. Are the early ASEs slightly different looking than the more recent ones? Everything else measures up (weight, thickness, diameter, ring test) so am wondering if there was a change in the look of the ASEs in this period
