Dan BrettaI don't know what it would sell for, but if it's obvious that it's Ty Cobb and you have an advertisement with him endorsing the product I'd say it's an easy money maker.
I've seen the Lajaoie fob sell for over $800 in an REA auction.
edited to add: I just reread your post - so it's a stamped likeness of Cobb and not a photo? That changes things. Might be worth about what he wants for it. Do you remember what the product advertised was?
