Is there a way to have a game used item MLB Authenticated after the game is over? For example, if you had an item that was game used last month (or whenever) can you have it authenticated using photomatches, player testimony, ect? Just curious as I have seen an item for sale that was NOT authenticated and then seen it a few weeks later and it WAS authenticated.

I guess my question isn't CAN you have it done, but HOW do you have it done?

Thanks
