Found this on the reverse of 2006 P Half Dollar. Copper layer showing through is pretty obvious. Does not look to be PMD, curious how this could happen. Also, does the that line extending from the "N" look to be a minor strikethrough or PMD? Thanks for any input.
Very interesting possibly a small Plating error,i agree it doesn't look Damaged @paddyman98.Don't see anything wrong with the (N)can you explain better.
The line in-between the copper spots make me think more of a lamination. Kinda odd that upper spot stops at the top of the ribbon.
The line from the N to the wing is PMD. The other appears to be a discoloration or stain, not an error. The lowest star and the ribbon seem to be the best clues.
That's a good point about it stopping at the top of the ribbon. If a lamination error should I be able to see defined edges? Re: discoloration or stain...it's definitely not either of those. Pretty clear with a loupe it is the copper coming though and that it is integrated into the design.
The tips of the bottom star should show color if it's a strike-thru, it goes around the tips of the star. Also how it stops at the ribbon top.
The tips of the lower star do show color, that would be more clear if higher resolution pics were allowed. But I am not asking if the color is a strike-thru...that was in reference to the line starting/ending with the N in UNUM.
The blue line from the N appears to be PMD The red lines raise a question about struck thru copper scrap.
Rolled thin cladding, I don't see the heavy edges that should be associated with a retained strike thru.
I don't see the heavy edges that should be associated with a strike thru. Agree Rolled thin cladding Should still show on tips of stars and would not conform with the lines in the ribbon.
@potty dollar 1878 Clad coins aren't plated I believe it's some finning or thin edge scrap containing the copper core that is a retained strike through. The line through the N to the wing is where some of it dislodged. I don't think it was a rolling mill issue because I feel it would have more elongation and distortion.
Perhaps a few tiny holes in the copper-nickel cladding layer before it was bonded to the copper core, which allowed the copper to come through to the surface during rolling.
Here's the sharpest I could get looking through the loop. There seems to be a defined edge near the neck at least. Still not convinced the line running though the N in Unum is PMD. Seems like that would have to be a hard hit....pic of obverse is below ...this is not an abused coin...but not an expert here so staying open minded that is may be pmd..just don't know how in this case.
Thanks for the extra effort on the new photos. The cut looks like it may have been damage to the planchet before striking. With how deep the cut is you would expect to see pushed up metal on at least one side of the cut.
Defective planchet? The plating didn't cover the entire planchet and therefore shows though after the strike. Just a thought.
This was my guess. It doesn't really look like anything is missing and the copper that is showing looks fully struck .... OTH maybe the original nickel layer was unusually thin in broke away in some spots, like in the v shaped area around the eagle's neck? Just throwing out ideas. Thanks everyone for the input!
