I pulled this card a few weeks ago from a box of 2012 Spx. I have been trying to find some way to put a value on it. More than one vendor at a recent card show asked me what I wanted for it but I had no idea what to ask for. It's not listed in Beckett, and the only other one I've seen is listed on eBay for a BIN of 300$, which I'm sure is over the true value of the card. If anyone has any knowledge to what this could bring value wise id really appreciate your input. Thanks
