Pokémon Vintage Folders

I found this box of vintage Pokémon folders from 1999, they are officially licensed by Nintendo and I’m not sure what to do with it. There are 48 folders in the box, varying in design. There are 10 with Ash, Pikachu and Team Rocket. There are 12 of Charizard, Gengar, Blastoise, Pikachu, Poliwhirl, and Cubone. There are 12 of Ash, Pikachu, Misty, and Brock. There are 12 of Pikachu and Meowth on a Pokédex. It’s in a small little blue “retail” or “display” box that says “Get It All” “Plymouth”. I want to know what I should do with these folders. Idk how to send a photo it’s not letting me 😭.
