AndyI am thinking about selling or trading two cards that have been in my collection for a while. I have a Cobb pastel PSA 6 with the over 300 back, and the Cy Young pastel PSA 6 with black back. Have not seen one auction recently, any idea on value? I saw previous posts give a 20%-50% premium for these backs, I didn't realize it was that significant.
