I have one but the set symbol is an M in a circle. Can not find this anywhere. Please help.
That would be the DotP promo. Star city has it priced at 1.49 (slightly played) to 1.99 (mint). Which happens to be the exact same price as the Mirrodin and Commander printings of it, and slightly less (a few cents) than the 10th edition print. So...it's worth the same as the other printings of it, it would seem.
