Die polish lines.

[nk1nk]

Love em or hate em? Post pics if you got them. I think they give character to a possible boring coin. This coin is not mine, I hesitated too long on eBay and missed it. I really like it though.

This topic makes me cringe at the memory of 20 page semantic arguments with Doug on Coin Chat.

Amazing pictures robec!!!

 

I'm not familiar with that thread Lehigh, if there was some nice pictures posted and you have a link, I'd like to check it out.

Closeups of this 1927-S Peace Dollar show quite a few. I don't always like DPLs, but these aren't too distracting and the coin is just so darn nice in every other way.

I'm having flashbacks. Post a trigger warning next time! haha

I'm with orifdoc, on PL and DPL they can be distracting, but add a little character on a "normal" strike coin.

Part of normal die maintenance and repair....but some work was performed better than others.

[grip]

Reminds me of a bad outcome after surgery .Patient not prepped correctly.

[dcarr]

These are often the result of efforts to efface clash marks on a die.

[PocketArt]

Finite but noticeable polishing on "21" Peace dollar. My pictures are not as nice but did see a bit of doubling when trying to capture polishing lines. Curious if Vam?

That particular thread on that chat board convinced me once and for all that I did not want any part of that place.

 

Some cool pictures so far.

im not a big fan of it but it sure looks nice

[physics-fan3.14]

There is a big difference in the coarseness of the die polish, based on the era and techniques. There are some, like the 30s-40s S mint coinage shown above, which are characterised by really coarse, grainy, visually striking die polish. Then there are some, like this quarter, which have very, very fine polish (only seen at certain angles under magnification). This is the only DPL Seated Quarter graded:

The coins suggest that the folks doing the die repair/maintenance were not very careful about using contaminated grit. An "emery stick" was just a wood stick with moist emery powder on it.

 

All sorts of info about die polishing etc. will be found in From Mine to Mint.

[lehigh96]

I was just taking a look at the McClure Collection and look what I found.

 

 

That is some serious die polishing on a 1923-S MS65 FB Mercury Dime.

[coinman1794]

You will see a lot of these Lincolns with heavy die scratches where the Mints were trying to remove clashing.

[RWB]

Lots of clashing left on the '23-S dime, too.

[PaulS.]

Check this one out!

[RWB]

Wow! That poor dragon.

[PaulS.]

Wow! That poor dragon.

 

Yeah, some worker at the mint must have had a bad day and took it out on that obverse die!

 

 

-Paul

[RWB]

Kind of looks like he had been playing in the mint's sandbox before work!

[david3142]

A lot of modern Lincolns have very strong polishing lines. This is one I just photographed in my raw Lincoln album:

 

[robec1347]

Those look more like plating bubbles David.

[david3142]

I see what you mean above the date, but what about all the lines? Do plating bubbles form lines like that? They are much more prominent in hand.

[robec1347]

I'm sure there are plenty of die polish lines. Bubbles come in all sorts of shapes, including straight lines. From the mid 80's through the early 90's these bubbles were very common.
