After being an avid collector of baseball cards for the past 25 years I've decided to set my sights on purchasing some autographed bats. I decided to take a peek at Ebay to get a general price range and it's about what I expected. What concerns me are the number of companies out there who claim the bat is legit with the official certificate of authenticity, other than PSA, Upper Deck or Beckett I'm not familiar with any other legitimate companies. Does anyone have any other online recommendations to use to shop for autographed bats and/or any advice on legitimate certification companies. I realize the autograph industry can be a shady thing at best but I'm trying to do a little homework before jumping in.
