National Sportscard Authenticators (NSA) is a card manufacturer and grading company. They sell game used cards slabbed in their protective holders of players from all different sports. On their website they claim that if they grade a card that has been trimmed or is counterfeit they will pay the cardholder $1,500.00. I wonder how that really works? If someone sends in a card for grading that they know it is counterfeit or trimmed and it comes back graded what is the person going to do? Are they going to admit the card was doctored? Probably not. Even if you sent the card in and didn’t know it was doctored and it comes back graded, how does that help? If you sent in a card in which NSA graded it you would have to remove it from the holder and submit it to another grading company like PSA or BGS just to get a second opinion. The whole thing seems a bit confusing to me. The serial numbering on the cards for example says “1 of 25″. Why couldn’t they just stick with “1/25″ for a serial number? The way they have the cards numbered makes you think they are part of a set and not serial numbered. Browsing eBay you can see that NSA cards don’t really sell that well. Most of them don’t even sell at all. Personally, I wouldn’t buy them, but thats just me. Has anyone else had any experience with them?
