It's from the original base set and - as lazlow said - it is a bit banged up. About $13 is a fair price considering the condition. Had it not been banged up, would have gone for more - closer to about $50 - as it is one of the most sought after cards from the original era. It is the premium foil which were the only rare's done in the original base set and the did fall roughly one in four packs - so it wasn't exactly easy to find. Had it have been the mirror foil parallel from legends ..... would have gone for a lot more.
