PSA 9 Joe Montana 1981 Topps #216 Rookie Card San Francisco 49ers

Gorgeous, PSA-graded 1981 Topps trading card of Joe Montana of the San Francisco 49ers. This is a PSA MINT 9 (Mint) but I cannot understand why it isn't a PSA 10. This card is protected within the PSA tamper resistant holder and is individually registered in an online searchable database provided by PSA. If we have multiples of the card listed, please note that the card pictured may be a sample image and a card of the exact grade advertised will be shipped to the buyer.
