Almost immediately following the celebrated release of 2012 Contenders Football earlier this week, the annual frenzy commenced as collectors across North America began scrambling to determine the relative scarcity of the set's ample selection of Rookie Ticket SPs and variations.

It's a captivating phenomenon that takes place every year and explains, for instance, how a base Rookie Ticket of New England Patriots speedster Jeff Demps can sell for $21.95 on Wednesday while another sells for $76.01 just one day later. Indeed, it didn't take savvy researchers long to figure out just how short Demps' RC is. (For the record, it's limited to 99 copies, while his variation is limited to just 25 copies.)
