Die polish lines?

Touche', sir. I didn't see page 2. Well I'm stumped

 

Typically die polish lines only show up on coins where the die was clashed and the mint tried to polish out the clash marks. And since a die clash can occur at any point in a die's life it may be a fairly new die or a well worn die.[/QUOTE]

Thanks GD

 

I am 100% sure my 1971-S was not cleaned. it was sent to Ngc with the coin still sealed in the mint wrapper that all MS/Blue bag IKE are put in.but the mint may have done something to it I know I did not.

 

If the striation lines from the rolling process are heavy they can survive the striking sometimes.

The fact that the lines are present on both sides of the coin and running in the same direction on both sides pretty much indicates that they are fom the rolling process.

 

Jello, that coin exhibits die polish lines, IMO. Just as struck, and NOT mishandling (they are obviously raised and go "under" the devices/lettering). I disagree with GDJMSP on this point.

As for the ldhair's coin. Color me confused. Can't be die polish as it goes through the edges of devices and fields. I would guess something was on the planchet to begin with, but even then I'd think that the lines would have been obliderated in spots that have a full strike.

 

I've said this before, and I'll say it again, but heavy posish lines absolutely can and do sometimes affect the devices. I see it on zincolns of the 1980's all the time. The coin below is nowhere near the most extreme example I've seen. Having said that, the coin the OP posted does not resemble any polish lines I've ever seen, but then again I only collect and search Lincolns.

 

ldhair, Have you sent a PM to James Sego (segoja on PCGS)? I'd be interested in what he would say about this coin, and who I would go to if I were wanting an expert's opinion.

 

Have you ever seen a coin with this effect to the extent seen on this Ike?

 

I may ask James but figured conder101 might see this and offer an opinion. He always seems to nail this type of thing.

 

Agreed, and just because Doug says he sees the same lines on the rim, doesn't make it so. I see the lines ending at the rim.

 

The coin was not whizzed and these are NOT die polish lines as the furrows you are seeing is the result of the planchet being cut from the end or beginning of the copper nickel coil. These coils were fed by hand into the blanking press feeding rollers and I've heard, that either the last few feet or the first few feet of that coil was sometimes pulled through the feeding rollers which caused the furrowing on the strip via abrasion from the rollers. This makes complete sense since the furrows all run in the same direction as shown on the coin I possess below:



This is not uncommon with Eisenhower dollars and I've even witnessed the same thing on a Georgia Statehood Quarter.

 

I see the same thing Doug sees.

 

Since these are on the entire planchet, it stands to reason that they would also be on the rims.

 

Okay, I see some of the lines not ending at the rim. Regardless, it seems that the mystery has been solved (see post above yours Jody). As far as the debate about die polish lines crisscrossing or on devices of coins, I absolutely refuse to have that discussion again. Anyone interested in reading that debate should reference the following thread.

The resolution as I recall was to refer to all raised lines on coins as the result of "die condition lines" thereby not violating the correct use of numismatic terminology.

 

Thank you. That is the first answer I have seen that actually meets the conditions I said it take to cause this.

 

Thanks for that link Paul. I see this has really been hashed out before!

 

I still have a headache from that debate. :arguing:

 

These may be roller marks or marks from a rotating descaling brush.
