I've listed and re-listed topps Red Backs Yogi (Larry) Berra and Warren Spahn on eBay for someone I know and they've got looks but no bids.. is there no market for these cards? eBay items 5231962148 and 5231962717 if anyone wants to see pictures..

Apologies ahead of time if that's not allowed in here.. call me a board 'noob' or something since I just joined and will follow any rules.
