Purchase autographs of all your favorites with confidence. Everywhere on our site where you see "w/COA", the autographed item that it accompanies comes with a Certificate of Authenticity from Collectors World guaranteeing that the autograph is real. Below are examples of the certificates.

The first one states that Mel Blount signed his autograph on December 2, 2000 and this was item #119 from that signing. The second one states that Kendrell Bell signed his autograph on December 8, 2001 and it was item # 133.

This way, when you purchase an autograph you will know what date it was signed on and what number it was in the lot. And Collectors World guarantees it.
