Two years ago I stopped by a rummage sale that was raising money for my local church, and amongst some old vinyl records that I picked up, I found a gallon zip lock bag full of Pokémon cards for $16. I took it home and found probably $300 worth of WOTC holos among bulk. Highlight of the bag was a fairly good condition shadowless mewtwo. As a broke high schooler it nearly doubled my collection.
I regret to inform that the theme deck was not sealed… it had all the cards in it except for whatever the random holo or reverse holo (I can’t remember which) it comes with. I didn’t even bid on it
