I haven't picked up many Ryan Roberts cards since he signed with the Rays. It's just different with him not being on the D-Backs. But, I did pick up his 2013 Panini Prizm Refractor Auto off eBay recently because I figured since they were numbered out of 25, they might not be on eBay for very much longer. I did a Best Offer of $7.50 with free shipping.
If anyone has the base auto or any of the Prizm Ryan Roberts cards for that matter and want to trade please let me know. Thanks!
