Not sure if these are lathe lines or just concentric polish lines. There used to be listings on errorvariety.com but the site is not available now. I couldn't find listings anywhere else either, just examples.

Well, for someone who generally has a sunny disposition, that doesn't sound too positive, Will. I get the feeling that's a no, along with a fair amount of ignorance for even starting the thread. Am I close?
I misspoke when I suggested it referred to the striking of the coin. I should have said the hubbing process. I would think it would eliminate the lathe lines from the incuse area of the die. The second link you provided makes the same suggestion. Under the heading "Multiple impressions from the hub were required to create a complete working die" (in your second link), he says: "Notice that the photo shows concentric arcs in both the field and relief. This is not possible using pressure transfer methods." Whether that is actually the case, I am not sure. But it sure seems plausible.

Did you read the whole thread from the NGC board? Rowdy, I don't know, that's why I started this thread. As you have seen, I'm not the sharpest knife in the drawer.
LOL. I wouldn't say that at all! Yeah, I read the entire thread. I don't know either, it's just that that explanation made more sense to me. I've tried to do some more research today, but have been a little limited on time. It does seem that there is no real consensus on the subject, so it makes it a bit more challenging to understand. Didn't Will do a study on lathe lines a year or so ago? I know he did one on die trails, but I was thinking maybe he did one on this subject, too.

I'm sure he did, that's probably why he's trying to kick me in the nu+$.
