I spotted a Dunhill on a lot of 4 auction a couple weeks ago on ebay. It wasn't listed in the title, and was in the description, along with three other crappy pipes. I could only see one angle, and had to ask if it had a dot on the stem. He said no. I passed, but watched the auction out of interest. It went from 30 to 100 dollars the last few minutes. I wondered if the person that won asked the same question.
I recently bought a handful of pipes on there for best offer. Most bowls were cracked all the way through, and I was able to return. However, they went back on ebay right away and the seller stated in tiny letters that there were small surface cracks, and resold them for more than what I paid. My guess is someone is not going to be very happy, or they may just clean them up and pass them off to someone else. Some people just don't know what they are doing, and think people are out to get the return and keep the item.
