Hard to tell the 'dark hue' by the pictures due to lighting... but this is definitely darker than normal... and the finish shows strange horizontal lines...   It's kind of like this one 2001 I found with lines through the obverse if you can see it...   Much easier to see in person, or perhaps just the right lighting and angle... whatcha think?

It is not sintered. A sintered coin would not have the lines. John1  Afterthought, A sintered coin could have roller lines on it.It still looks like a non sintered coin with roller line staining.

I can try again to get better angles and lighting... for now, I just have it in a plastic sleeve in my pocket to bring to a dealer to look more closely at it.
I was wondering if it was missing clad on both sides... but it's typically just on one side... and, I've not been in the game long enough to know the signs...

Looks like roller lines to me.

Roller lines hmmm... perhaps from when the planchet sheets were formed?
The lines do appear to go through all the dips and valleys in the strike...
Are they a common issue? I just went through close to $2000+ dollars in quarters and these were the only two obvious examples I found of parallel lines running through the coins...
And the 1978 with a discolored patina is the only one that looks like a possible mint or dip issue compared to dirt etc...
I haven't separated out any coins for errors or high ms grades yet... but these two just stuck out as being different...

Neither coin is missing the clad layer. If it was,it would look copper in color. John1

Quote: Roller lines hmmm... perhaps from when the planchet sheets were formed? Correct. Quote: Are they a common issue?

I have seen them on 95% copper cents a lot more than clad coins.

Quote: It is not sintered. A sintered coin would not have the lines. Asking for the sake of becoming more educamacated. I read on this thread: Quote:Quote: Roller lines hmmm... perhaps from when the planchet sheets were formed? Quote: Correct. I had not heard of roller lines before. The above quote indicates the roller lines are made when planchet sheets are formed. The planchets are then cut from this sheet. The planchets are annealed in some step after this. So does annealing remove roller lines so a black beauty never can have them? Please enlighten me.

I'm starting to see this more and more now that I'm starting to look for it...
I've seen it quite a few times while sorting through my dimes now.
