I don't know 100%, but the Bobby Allison autograph I pulled from a pack myself from the NASCAR set was just the regular card with a silver ink autograph on it. No special autograph markings on the card at all, no COA. Just a base card that had been autographed. This is just like that so I would feel pretty comfortable in this being legit.
VERY slow trading due to health problems. Not transferrable so safe to trade with, just moving is painful and can't always access the cards.
