The rarest NFL card is considered to be the 1935 National Chicle Bronko Nagurski. However, with the advent of Panini National Treasures, which produces 1/1 cards, any Panini 1/1 card is technically tied for the rare football cards. The rarity of a card can be determined by checking for the print run, which is often included in the design of modern card releases. Many card manufacturers also release print run details for print-to-demand card sets.
The most valuable NFL card as of 2021 was a Patrick Mahomes card, graded 8.5 by BGS, which sold for over $4 million. Three 2000 cards featuring Tom Brady also made the list of NFL cards to sell for $1 million or more. Other valuable cards include the 1981 Topps Joe Montana Rookie Card #216, the 1933 Sport Kings #4 Red Grange Rookie Card, and the 1998 Playoff Contenders Ticket Peyton Manning Auto #87.
The value of a card is influenced by several factors, including its rarity, condition, and the demand for it. The rarer a football card and the higher the demand, the more expensive they become. NFL trading cards can become a rare commodity when new cards get released, or vintage cards receive higher grades from renowned grading companies like PSA and CSG.
