Old school pokemon.

Im not quite up with the lingo so I apologise if I get anything wrong. I have a topps tv animation edition charizard tin and the big shiny card which is 5/5. not sure what that means. ive checked all over the internet and am yet to find another one? so have no idea of a price to sell it for? its not in amazing condition but all of the cards inside are. they are also the topps tv animation edition cards, Online it keeps saying a set is 90 cards but I somehow have 112? Any advice would be hugely appreciated.

Scans/photos would be super helpful. :blush:
