Hi there,
I have been collecting autographs since I was young, and have gotten more and more into the hobby the last few years. I am however only now starting to really scrutinize certificates of authenticity and look for signs of forgery. I bought a Mickey Mantle baseball on ebay and am not sure if it is authentic or not. The fact that it is an old mel stottlemyre special league baseball is promising to me, and I think I see a small crossover loop in the Ms, but I honestly am not sure and would love other opinions.
