Life is short. A pipe should be enjoyed, not become a source of frustration nor suffering (when a pipe is really awful, and there are many out there). A good quality pipe should provide pleasure from the start, or after a few pipefuls.
With this in mind, I have sold some. I have donated quite a bit for veterans. Those who were decent but were not for me. I have thrown some in the garbage bin. And I have burned some, the nasty ones, the truly evil ones, in my wood stove.
I have done the same with tobacco.
