Help With 2017-P LSC Lines Behind The "Um" On The Reverse.

That's from multiple coin contact marks from other coins. Not an error coin. PSD.

I apologize I know I am really new to everything but I am confused on how the PSD did not strike through the letters just straight strikes behind the letters?

The letters in question are incuse, recessed into the metal. The lighting makes them appear raised, which makes the lines appear to be behind the letters, when in actuallity, the lines are passing over the letters.

Those letters on the shield are incused on the shield. meaning they would be raised on the die.

I don't see any damage to the copper layer to suggest it happened after the strike, which should be apparent if it were. could be contact marks from a reeded edge, but they look like impressions, not scrapes, and if they were scraps I'd think there would be some copper loss.

The shield itself is the high point in that area of the coin, I'd think if it was PSD the zinc would be clearly exposed if it were this deep, they aren't down to the bottom of the "M" but they are close to it. but I don't have an idea of what could put raised lines on a die, unless it was a strike through of some sort and the M crushed whatever it was being the higher contact point.
Perplexing. I'm not a professional at this, doesn't seem like PSD to me. I hate these reverses, hard for me to figure out what are high and low points on the die with incuse and relief on the same coin. rises on coins are lows on the dies, lows on the coin are rises on the die.... Jeesh. and Lincoln shield cents have both, and middling relief as well.

Yeah I feel like it should be some sort of strike through something. but I guess it also could be a planchet issue before plating that doesn't get obliterated on the strike in that middling, not too deep, not too high area of the shield. that spot isn't a high or a low so it doesn't get the most of the push of metal or the fill like the letters do. maybe less metal movement leaving those marks that were on the planchet before plating behind after the strike possibly.... I dunno.
I think I've thought about this too much. lol

Silverwolf, I was correct. It is PSD. Coop weighed in on it, and my assessment is correct.

regardless of what the lines are, they are not coin contact marks. The odds of that many uniform hits, all in a row, is out of this world..

I don't know what coins you look at, but the ones I check out the letters are most definitely raised :confused:

Cheers
