Today I was looking at an autographed baseball by Dizzy Dean. The COA was from K Gold Collectibles. So I searched the Internet for K Gold Collectibles and found nothing. Maybe there is something out there, that I didn't find, but a legit COA company like Steiner Sports would come up with all kinds of hits. I have found and bought some cool baseball items that were not autographed from Auction Zips and will continue to use them for that, but I caution anyone from buying an autographed item from this Auction site and they don't see to check out the validity of the COA's. If I am wrong, Auction Zips needs to inform me that they validate all COA's.
