There's one here on eBay with an opening bid of $1.00, numbered to /250. It's all dependant on what someone is willing to pay. Some may pay up to $25-$35 as mentioned above, but others only a few bucks (I fall into the second category; this card would have no place in my collection so there's no way I'd be paying more than $5 including shipping for it).
I'll never quit collecting entirely, but I am downsizing. Check out my COMC store and help me thin out what I don't want so I can buy cards that I do want. See something you like? Send me a message on here, and we can knock the price down quite a bit. I'll even take a bit of a loss if it means getting you a card you really want.
