What those two bottom macros show, thats interesting, the longacre doubling is prominant on the right side, that is from the main hub. now, there is no doubling on the date. that is becaue the date was punched direct into each coining die, after it was made from the hub. Then, the die was polished (ground) but not so much as to remove the longacre doubling completely. There was room for one more relapping left in each die, it seems, which makes its own die state

<< <i>What exactly are they >>
They are thin, random raised lines in a coin's field, usually in great abundance.
<< <i>how are they created >>
Files and emery cloth or other abrasive substances used to eradicate unwanted features or blemishes on a die will often leave scratches in the surface of the die face (field), which transfers as raised lines on the coin.
<< <i>are they desired >>
It is one of those 'eye of the beholder' things.
<< <i>can you get rid of them >>
The easiest and quickest way to accomplish this is to spend the affected coin.
By the way, not all of the coins pictured in this thread exhibit die polishing lines. The devices (portraits in these cases) will not have die polishing lines. (PMD is a more likely attribute for a couple of these coins).
I agree totally, Very Cool Coin

Nice clashed dies showing "Liberty" through to the reverse.

In fact some on some coins the polishing of the dies might have resulted in better looking coins than was struck prior to the polishing. Again I'd say it just depends on the coin and how the lines affect the overall eye appeal of that particular piece. At least that's how I see it. What do I know though... I like die errosion lines too
