I know everybody here collects cards, but I think some of you may also collect 8x10 photo, basketball, or jersey, which signed by your favorite player. I've read a lot of articles about real or fake COA, but I'm still not sure which one should I believe that it's an authentic one. I have 2 items that certified by the different companies. The first one is World Wide Authentics. I think this seller just made it himself 'cause it's printed out in an A4 paper using Microsoft Word. The second one is from Sports Centre, which I read from a source on eBay and they said it's a good COA company. By the way, it said on the COA that I can log onto
www.scatickets.com to check and confirm my item serial number. After I log on that website, I couldn't find anywhere that I can do so. Recently, I found an item that certified by D&B Sports. Is it reliable? What should I check out exactly on COAs?
