$50,000 for 200 pipes breaks down to $250 per pipe. The issue is that many of these exquisite pipes appear to be by long forgotten makers. There are BBB's, which could get that kind of price or more, what looks like Orlik or Imperial, and a number that I can't quite make out. So some of these might not get $250 at auction. I'm seeing some with damaged amber stems that have been shortened and reshaped. It's also a specialist's collection, which means a limited number of buyers, especially for 19th century pieces. The condition looks to be excellent in the main, but I wouldn't want to own 200 pipes from this era. They're fun to look at, but not always fun to actually smoke.
Is there more documentation on this collection, such as makers and dates? Is there better photography of the individual pipes so that a potential buyer has a better sense of their condition? Owning pipes from this period I can attest that there are always surprises, some good, some bad. For $50,000 I don't want any bad.
