I do not spend a lot of money on autos or game used cards. I like to find bargains of Cardinal players for under $10. One exception was the 2009 SP Authentic Kyle McClellan By the Letter autos. SP put out cards that spelled a player's name, team name or rookie. McClellan is the only Cardinal I know of that has cards spelling his name. I met him at a small card show back in 2008. He was a nice as can be so I decided to try for this set. The Y was the last one I needed, bought it off EBAY in November 2014. I believe the most I paid for any of these was around $12 delivered. All cards are numbered to 30.
