There are so many factors that impede on this situation. How many people are looking to obtain this card, what they are willing to pay for it, what you think it's worth, etc. If you were to put it up on eBay, I think that you might get $15-20 for it, but then again you MAY hit that bidder that is looking for this exact card to finish their set/add to their PC and fair pretty well.It's always a tough situation to have, but in the case of 1/1's it's a good one. I had a 1/1 plate of a nobody go for $18 to his brother, but that means that there was someone out there willing to bid him up that high (sounds like nothing much, but in the way of eBay, it's a good amount!). I would personally set the TRADE value around $30-50, and the SALE value to $20-30. Hope that this helps you out a bit. Best wishes on getting what you would like for it!
