Event Update: This Sunday's William Perry Signing Has Been Postponed.

CSAC Authentication Center

To verify the authenticity of your item, find the number on the holographic sticker on your COA/Item and enter it below. You will be directed to a page with the signing details and photos from the event if available.

CSAC has become one of the most well respected and trusted sports memorabilia information service organizations in the country. We have built relationships with consumers and businesses alike and have become a vital part of many blossoming sports memorabilia collections.

Now, for a small fee per item, you may purchase a CSAC COA for your item when purchasing CSAC autograph tickets. The stickers are tamper resistant and if removed, voids the authenticity certificate. COA's holographic stickers provide the best insurance that your investment is proven authentic.
