Specialty Yu-Gi-Oh! cards can be expensive and run in the thousands of dollars, like Doomcaliber Knight, worth about $700, and the first Japanese promo version of Dark Magician Girl, which could set you back about $1,100, but they don’t come close to the price of one particular card currently on the market. Card Shop Spiral specialty store of Tokyo is selling a card called Blue-Eyes Ultimate Dragon for a whopping 45 million yen ($406,800).
