Nearly all pipe owners have fantasized about making money on their pipes though re-sale. There's a joke about boats being holes in the water into which you pour money, and pipes might be said to be briar woodpecker holes into which you pack money and burn it. What is the future (or are the futures) of used pipes for sale? They could be like snuff boxes; now that few use snuff, the snuff boxes once used by the rich and crafted with great artistry now sell for high prices simply to look at. I'm not sure anyone is going to be marveling at Dr. Grabows behind museum glass, but Beckers maybe? I hope no one is planning to retire on resale of pipes.
