2007 SP Authentic hobby box


2007 SP Authentic is a 162-card set released by Upper Deck on November 20, 2007. The By The Letter autographed manufactured letter patches that debuted in the previous year's product return, this time as part of the base set. Each 24-pack Hobby box will yield two By The Letter cards.

In addition, a series of unannounced "gimmick" cards of Alex Rodriguez were randomly inserted into packs without prior notice -- although mostly received by The Hobby with ambivalence.


24 packs per box, five cards per pack (MSRP: $5). Hobby only.
