Lost box containing a rare collection of about 200 Pokémon cards, including holographic and first edition ones, at a flea market.

I misplaced a box containing my rare collection of Pokémon cards while visiting a flea market in the Northern Panhandle last weekend. The box has about 200 cards, including some holographic and first edition ones. I remember setting it down next to a table while I checked out some items, but when I returned, it was gone. This collection means a lot to me, and I really hope to get it back. If found, please reach out!
