My best pull ever was a 2001 Fleer Red Sox 100th BoSox Sigs Nomar Garciaparra Autograph out of 2002 Fleer Genuine, that booked for $250 at the time. I traded it for a nice Clemens auto.
the best pull of my life so far was today. i bought 5 packs of 05-06 topps '52 style and pulled a magenta mickey mantle press plate 1/1!!! my first 1/1 to boot.
