I kinda agree with @tpugmire in some regards. I have items that I can't use (don't have the necessary console) or just extras due to eBay splurges that I don't really consider part of my "collection." Physically, I'd probably put them in a separate box (if I had the room), so I guess that'd be like having them on a totally different list and not having them count in my total number of items.
