Game-used authenticator(s)?
 

I just picked up this finger sleeve used by Reggie Miller at some point during his HOF career (he wore one every game). Does JSA or another company authenticate non-jersey items, say like this, a batting glove with a player's number, helmet, etc., based on matching it to the known style of what they used during their career? Thank you for any insight.

Mei Gray does. Also I believe PSA has started doing it as well.

Thank you -- I looked into both. Looks like PSA would cost $500 w/ cert -- no way worth it for this item; asked Mei Gray for a quote.

500 bucks! Buwhahaha! What would they do? Swab it for Reggie’s DNA? What a scam.

I am assuming photo matching.

I don’t know if many 3rd party authenticators provide this service, but I know auction houses do if you are looking to sell. They typically try to photo match the item like Jamie mentioned.
