Die polish lines?

Thoughts? All lines are raised. In a good holder as MS64.

That's what it sounds like and looks like to me. Great toning on the obverse! TC

 

Very Attractive, did you "Sharpen" the picture when you editted it?

 

I agree.
Are you SURE the lines are NOT on the holder?

 

Did not know this! Learned something new today.
So what do you call those lines that occur on a ton of early '90's cents? Die scratches?

 

After closer examination, I agree that even though these lines are raised (indicative of die polish) it seems that they do cross the raised devices (indicative of post strike polishing) as Doug points out. I am guessing now that perhaps both occurred. However, that does not explain the almost gem MS64 grade. Seems like the TPG saw it as die polish or perhaps liked the eye appeal. This is indeed a coin with an interesting story. TC

 

I KNow for a fact that I have coins with Die Polish Lines on the devices......Im not talking about seemingly straight lines like the OP's coin but true blue die polish. Also I wouldn't rule out die polish lines for the OP's coin...........its just way to hard to tell

 

By FAR, the most attractive Ike I have ever seen!

 

I give! I have no clue what is going on here. Every time I see something that says it the line are due to the planchet, die, etc., I then see something else that tells me it cannot be what I was thinking of. The only thing I can come up with is something happened after the metal was rolled but prior to minting that affected both sides equally. I am at a loss as to what that could be.

 

1971-S 40% Silver w/polish lines

I too have a 1971-S with Die polish line and there not on the Ngc holder

 

Do die polish lines indicate an early strike or later strike when they were trying to cleanup the dies

 

I'm years too late but wish I had imaged the coin before sending it to PCGS. I thought it would come back a 65.
I also ruled out die polish and die cleaning because of how I believe the process is done. Maybe there is a process we don't know of. I wondered if these are stretch marks on the blank, creating a difference in hardness the strike could not remove. The way the toning follows the marks got me thinking about a hardness issue. Also thought of maybe a hardness issue with the die itself at some point when being made. It's an interesting coin that I will probably never really understand.

 

I agree completely. I would definately upgrade to this coin if I saw it in my local coin dealers display. I cannot figure out what caused this. But, I would agree with Doug that it's post strike.

 

I would sooner think that it was air in the top layers - both of them. However, the problem with your theory and mine is that there is no reason to believe that the obverse and reverse layers had anything what so ever to do with each other and yet they have the same lines in the same direction. I really don't think so.

 

Is it possible it was a planchet problem? For instance, the lines were left after the strips were rolled out, and they were strong enough to remain after minting.
