Card show purchase

I went to a local card show in a mall in Lancaster, PA on Saturday. Was a pretty small show not much to go though but was able to find one dealer with a binder of $1 Autographs and Jersey cards.  Selected the following 3 for $3.
1) Matt Diaz - 2003 Bowman Best #BB-MD.
2) Thomas Diamond - 2005 Bowman #160.
3) Andrew Carpenter - 2010 Topps # PPA-AC.
