I have a customer who has what is said to be a game used Jimmie Foxx bat. It comes with a Mears letter with a rating of an A7. The letter states that there is no record of Foxx personally ordering a bat, but there is a record of the type of bat being in the team order. What exactly does that mean? Is this still considered a game used bat? And how does that effect the value? Thanks for anyone who can help!
