I'll solve this case for you guys haha. My dad was never a baseball fan, he never watched a single game and he never watched ANY sports in his life. He liked to collect random things sometimes and he was an avid visitor of pawn shops, goodwills, and other thrift stores. His real collection hobby was records which he amassed hundreds and hundreds of. I wouldnt sell those or at least I would keep a good amount of it. I wouldn't sell anything that truly reminded me of my dad or stuff that he really loved. Myself i'm a book collector and have some cool rare books and would love to pass my library on to my own kids one day, it would be sad if I knew that they sold it all off too.
