(LONG POST, ADVICE APPRECIATED, THANK YOU) What's up guys. So I'm working on a collection of autographed MMA memorabilia. I've been scammed before so I've become quite savvy at detecting fakes. I see a lot of stuff on ebay and other sites that offer signature pictures, posters, etc., however a lot of them aren't certified by PSA/DNA or JSA (James Spence Authentication) but appear to be quite legit. At any rate, I came across this website: https://mmasignatures.co/ that is loaded with tons of rare autographed merchandise. However, this person often uses their own authentication service through their company and claim: "Our head authenticator, at our authentication company is a top guy at JSA as well. That is for items others obtain and he will authenticator or reject the items." Here is an example of an item he has for sale with one of their certificates of Authenticity: Here is a brief conversation I had with them via email: Not only do the signatures on his merchandise pass the eye test (I've compared his autographed hendo merchandise with an official UFC event poster autographed by hendo I have and they appear to match), this dude has a Facebook page with lots of 5 star reviews and a legit twitter account with pictures of him at expo's with fighters. Link to Twitter: https://twitter.com/AJMMASignatures Link to Facebook: https://www.facebook.com/mmasignaturesusa/ Anyways, my questions to any of you willing to read this and give advice are: Would you buy from this guy/website? And do you trust the legitimacy of his certificates of authenticity? Thank you very much.
