I only bought one vinyl and not that it will prove anything for certain but JSA has a show nearby in April and I’m planning to take mine to to see if they authenticate it. I wouldn’t really go through the trouble except I have $150 credit with them and need to use it on something. They found my 2 Michelle Obama signed books from Oblong inconclusive and credited me which I didn’t realize they did. I figured if it didn’t pass that you just lost out since they did do the work checking it
