I have an Upper Deck "Mark of a Legend" Joe Montana Autographed card from the 1995 SP set. I haven't ever seen one for sale, so have no idea what is worth, other than its probably worth a bit. Picture to follow, along with photos of other Montana and Rice cards I have
I have all 80s Topps Rice and Montana (and all 49ers) if you're interested. Too many to photograph; you would have to let me know exact cards if you're interested. All at least PSA 7 or higher; stored very very carefully.
