Quoted from ForceFlow:At least a pin can give you and your friends hours of entertainment.
This right here. I had a very large and expensive collection of Star Trek trading cards from the 70s. I realized I was the only one who would ever enjoy them, and they weren't even on display. I sold them all and put 3 Star Trek pins in the basement instead so I can enjoy them with other people when they come over. I did keep some of the autographs and unique cards though.
