How much is the Japanese CD promo Charizard? I want to know it its worth me selling mine.

How much is this double stamped misprint Milotic-Staff-Prerelease worth ? I brought it from trollandtoad last month.

I have unopened packs of neo genesis and the original Japanese 1996 pocket monsters original release and fossil release. I made a thread that had a pic. How much do they go for?
