While the value for such cards is not publicly announced, you might want to visit an appraiser for finding its worth. Another way to get the best possible deal is to sell it on e-bay. You can set a very high price for the sale and you will have folks come in and bid. These fans know what the market value is so they will try and outbid each other till the very end. More often than not, one gets more money than its worth on e-bay due to a bidding frenzy. If the final price does not need your expectation, simply close off the auction and you will get a pretty good idea what people are willing to pay for it.
