The listing, Yu-Gi-Oh Dark Magician Card Holo Ultra Rare has ended.
I've found a stack of Yu Gi Oh cards in my son's room after he's left for college. This is by far the most rare. See that they are selling on eBay for anywhere from $8 to $40. This one, unfortunately, is in very played condition and has a crease right in the middle of the foil. I am not an expert and no idea what these cards are worth. This is a first edition card. Numbers: SDY_006 and Letters ATK/2500 DEF/2100
