I found recently that some of the albums and series I have worked on in the past no longer interest me, or I never really was interested in the first place, but felt obligated to collect them because they were there. What do you do when you no longer what to collect say kennedy halves or lincoln cents, do you just get rid of them, or use them as trading material. I mean I don't want to continue actively buying coins for a set that I would never have the intention of finishing, but I don't want to get rid of the coins because I spent all the time and effort to get that far. What's a collector to do?
