For sale one of the rarest Pokemon trading cards is the Pre-Release Raichu cards because only 10 to 15 cards are available worldwide. One card would be worth over $10,000. It’s said that the elusive card was erroneously created during production of the prerelease Jungle Clefable, and the accidental cards were given to employees of Wizards of the Coast. The existence of Prerelease Raichu was made public in 2006 when a former Wizards of the Coast employee came forward with an image of the card and the story of its origins. It’s believed that eight or ten copies of the card were produced, though Wizards of the Coast does not acknowledge its existence to this day. Those who have obtained the card are said to have paid more than $10000.
