I have a Professor Elm's Training Method and a Mary's Request, both with silver borders. On the back of PETM, instead of the usual pokeball logo, it says World Championships 2004, and Mary's Request says World Championships 2006. Are these worth anything, or should I throw them away? Back to back posts merged. The following information has been added: I looked around some more and found Mary's Request on ebay, Buy It Now for $.75. I guess the other one is probably about the same.
