Online Price Guide
Can someone tell me if there is a site policy about trading OPG checks? I have a sub to baseball, but I have a few non-Baseball cards that I would be interested in getting prices on for trading purposes. (And yes, I know some people don't care about bv). I would love to find a FB or BB collector looking to trade for baseball price checks on a few items, but I think I read on here months ago that it might be against the rules. Any help is appreciated.
Here are the cards I am looking for help with.
