I need to let some of my pipes go to new homes, but I am having a tough time. The first time I sold off a large portion of my collection it was in order to pay for my wife and I to get married. The big deciding factor on which ones to sell off was how much they were worth. If I could make decent money on them, they had to go. This time it is different. I need to sell some off because they are getting neglected. The bits are starting to oxidize because I never smoke them, or even handle them anymore. Before too long, they are going to fall into a state of disrepair that will render them worthless. I have been cleaning the cob webs off of them, dusting them, and polishing the bits, but I don't always have time keep all of them clean. They also take up a little too much space. I just plain have too many pipes. I only smoke about once a day, and there are only about 10 pipes in my collection that are my "go to" smokers. Right now I have about 50 pipes left, and a display case that will comfortable hold about 30 pipes. So, the deal I have made with my wife is that I will cull it down to only what will fit in my display case, and if I bring a new pipe home, I have to get rid of an old one. That means I have to decide on about 20 pipes to sell off, and I just can't make up my mind. Almost all of them are good smokers, and the ones that aren't great smokers usually have some sentimental or esthetic value that makes them tough to part with. So, my question is: Have you had to sell off parts of your collection, and if so what criteria did you use to decide which ones got to stay and which had to go?
