It sounds to me like you have two different pipe interests. You enjoy smoking, but you also enjoy collecting, and you feel these are, for you, two very different activities. If I were you, I'd just accept that, and decide which pipes that you own, and which pipes that you buy, go in which category. There are pipe collectors who don't smoke at all, and enjoy that. You have both interests, so just be decisive about which pipes are strictly your collection and which are your smoking pipes, and stick with it. Next you will have to decide if this division is strictly made by price. Do you want to smoke only your less expensive pipes, or do you want to smoke some of your higher priced pipes? The idea with both activities is enjoyment, so only you can determine that.
