The price of football trading cards is determined by the card's condition, year of release and featured player, according to eBay. Additionally, special edition features may increase the price of football cards that contain special edition inserts or autographs and those that are refractor, parallel or game cards.
Football card collector organizations, such as Beckett, Tuff Stuff, Football Card Price Guide and Trading Card Central, release price guides or magazines for cards. Condition runs from the most valuable pristine, mint and near mint condition cards to poor. Tears, scratches, scuffs, stains and creases all lower the condition rating and the value of a football card.
