are topps pokemon cards valuable old valuable? My dad found his old

1 Gruul Signet

Mew VMAX (269/264) This single isnt just one of the most valuable and visually appealing cards in the Fusion Strike set

(1/19/2018) You don't own the cards you play this way

The condition of the Pokmon cards was listed by Gouldin Auctions as Gem Mint 10 which to the uninitiated refers to the cards featuring four perfectly sharp corners, sharp focus and full original gloss, no grubby stains with some allowance made for printing errors, if they dont impair the overall appeal of the card. What also helped the collection fetch for such a wild prize was the inclusion of shiny Alakazam, Blastoise and Chansey cards but above all else, it included the Holy Grail of classic Pokmon cards a first-edition, shiny Charizard

Personally, I think my quest is satisfied for the time being
