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 $5  fee per item, you may purchase a CSAC COA & matching sticker for your item when purchasing CSAC autograph tickets.
You will receive a CSAC numbered holographic sticker for each of your signed items along with a certificate with a matching  numbered holographic sticker.
The stickers are tamper resistant and if removed, voids the authenticity certificate. COA's and holographic stickers provide the best insurance that your investment is proven authentic.
