Hey all. So my neighbor, young kid early 20s, died a few months back. Overdose, pretty sad stuff sorry. Umm anyways his mom earlier this week knocked on the door and asked if I was interested in going through his stuff and taking it in to donate to guys at work (I work at a substance abuse treatment facility). While clearing out his room, I came across a huge box of Pokémon cards. I just want to know if I have anything good? What do I do with them? Grade them? Bring em to a shop? Any and all help is appreciated.
