Except that it's the smart thing to do. If I got a Black Lotus card from Magic the Gathering for only 25 cents at a garage sale, you'll be damned sure I'd try to sell it for the $27,000 that it is valued at.My personal advice: please don´t do that, if you want to sell, sell for a reasonable price. You got lucky to find it in a store for $12.99 and maybe you don´t want it, but there´s no reason to try to make someone pay 4 times it´s value.
Edit: But now that it's out of the package, it doesn't even matter.
