About a year ago, Jim Stinson put up a large lot of signed 53 Topps, including several tough ones. At the time, I didn't know him from Sam Hill, so my thought process was 'eBay auction + tough autographs - TPA certs (I know, I know) = probable fake'. If you go out to the sidewalk near my house, I think you can still see the indent I made from head banging there after I found out that he is very reputable. A bunch of them went for less than I would've paid.
