First time buyer from Sgaynor who recently purchased 2 autographed memorabilia. Submitted one, Ted Kennedy index card, to a well know authentication company - JSA. Came back not certified as authentic, which was not consistent with seller's statement that it was "guaranteed to pass 3rd party authentication". (I provided pic of rejection letter from JSA). With many positive reviews of this company I took a chance and lost. I was refunded my payment. Buying unauthenticated autographs is a gamble for anyone and I took the risk, but if the seller was 5 stars he would have offered to refund my authentication fee as well and taken the loss himself, given his word was that this was a legit signature.
