I think the issue is that it seems you're looking for the cheapest pipe you can find that has "Dunhill" stamped on the shank. I think that's the wrong approach, which is why these first two pipes are in such hopeless shape.
A good, smokeable estate Dunhill is likely going to cost upward of US$100. I've gotten some on eBay for a little less, but that was ten years ago. If you want a Dunhill worth smoking -- and one with a strong likelihood of staying with you the rest of your life -- then you need to be prepared to spend the appropriate amount of cash.
But as others have said: A Dunhill doesn't have to be your first pipe. (And it probably shouldn't be, unless you can find a good one at a crazy-low price.) Since you don't even know if pipe smoking is something you'll commit to, it would make sense to start with a pipe in the $50-75 range. (Yes, you can get a corncob for under $10. They're fine. They're just not something I'd ever praise.) This would be considered a lower-end pipe these days. But with that budget, you can get a smokeable pipe that you can "train" on -- learning how to pack properly, tamp when necessary, smoke slowly, clean and maintain, etc. And with the money you save from not buying a good Dunhill, you could pick up a wide range of tobacco blends to try, so you can figure out what the different styles are like and what your preferences might be.
So: My personal feeling is that if, as a new pipe smoker, you're willing to spend $100 to get started, your money would be much better spent on a less-expensive pipe and a good variety of tobacco blends than on a single pipe that just happens to have "Dunhill" stamped onto it.
For lower-range brands, I've been really pleased with the quality of modern Comoys and Stanwells. In the under-$100 range, I don't believe GBD is a good contender; Peterson is very good, but just hovering around this price point. I've been very surprised at the quality of the Trypis line from Canada, which starts at $35, I think. And there are literally dozens of no-name or house-branded pipes out there for less than $50 that provide a perfectly good smoking experience.
