OK, this is embarassing as I've been collecting pins for more than a decade, but I've never really displayed them properly. I decided to go the route of a 3-ring binder with baseball card sheets as holders. Questions: 1) Does one actually pin the pin into the holder by placing the backing outside the plastic sheet, and 2) Many pins do not fit in standard baseball card sheets, so what is the next most common/popular size? Thanks!
