How much should I ask for these baseball signatures? ?

I would say a die-hard fan of either of those players would probably buy either of those signatures for $100. They are not popular players so if you put them on ebay you would probably not get too many bids if any. I honestly think the cost of them combined maybe like $35 at most. Sorry if you wanted them to be higher. Look on google shopping for their autographs. Travis Lee is selling for about $10 for a signed baseball card.
