I'm having a problem returning a couple of Mewtwo cards I recently found hiding in the back of another hobby drawer when cleaning it. Among the 52 1st edit pokemon cards were a Mewtwo Legends and The Temple of Mewtwo. I remember purchasing them for my daughter at a young age. She played with them for about a day and became uninterested. I totally forgot where I had put them. As I was ho humming through them I noticed BOTH cards I mentioned are missing about 1/4 of the back of the card. The fronts are fine but the backs are incomplete. I feel like I have been unfairly compensated for the money I spent and would like to return these cards for fair compensation. I understand the time that has past but the company is still around and doing well.
If anyone has any information as to where to send them back or a web site or ???
Please let me know,,,and thank you.

Newly discovered. While cleaning out an old crafts drawer, I found 54 gen 1 Jungle poke'mon cards. A couple are in bad shape (peeled or rubbed off spots) some have little bends...etc. But man what a find. Here are some pics. Would like to sell the entire lot as a package deal. Let me know if interested.
