For me, I collect a lot of autographs and memorabilia. If you collect it, you want it nice. If you collect stamps or coins, you pay more for higher grades. If you collect plates, you donít buy ones that are chipped. If you collect comic books, you donít want the edition a 7 year old colored all over. It is no different.
When it comes to signing stuff, know who you are. I say that because I get why Buehrle may not sign Perfect Game, or Thomas and Maddux donít sign HOF. But Like, Steve Stone for example is notoriously a jerk to fans at signings. No Cy Young, No Sweet Spot, everything MUST be inscribed. You would not get back the 20 buck cost of an MLB Baseball if you sold a sweet spot cy young Steve Stone ball. Get over yourself.
I never am ungrateful for a player signing, but I do get why people get upset. Soxfest one year, Freddy Garcia showed up totally drunk and hungover, and this guy had been working on a World Series team signed ball, and Freddy Signed it upside down, so his signature is the only 1 going in the other direction.
