I have yet to find a pipe or anything pipe related at a yard sale, but I did find four pipes at a church sale once. I got two MM cobs, a beat-up, dirty old Pipes By Lee, and a Dr. Grabow that I could tell was only smoked a few times. The Grabow and cobs have since become favorites. The Pipe By Lee is a beater I carry in my pocket sometimes. I got all four for two dollars. That was a good day. Congrats on your haul. It's always wonderful to find treasure among junk.
