Quote, '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. |

The lines definitely are not passing over letters. It doesn't look like contact marks to me. Here is the reason why I was thinking this to be DDR  I'm still new just like OP so I don't know! Cheers |

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 |

The devices on the EPU is set deeper into the design. So contact on the coin will leave marks on the higher surface. It is PSD. Note on the last two images you can see that the lines are cut into the coin. The devices are still lower than the EPU. When it reaches that a deeper point, you will see the incuse devices affected:  When the coin is rotated 90 degrees it is easier to see the incuse EPU better. This coin had marks as deep as the EPU so it shows on these images:  |

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

I still do not see those lines going over the letters. If it was damage, the letters would show the same line all the way across. I don't know though. I'm not a pro, just tell what I see!

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.. |

The letters are not raised, they are recessed into the metal. If they were raised, yes, the lines would go through the letters. But they are recessed. The impression of the letters are lower than the surrounding metal. When the surface gets scratched, the scratch mark doen't show on the letter because they are lower than the scratch marks.

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

The letters around the rim of the coin are raised. One cent is raised. E Pluribus Unum is not. It is incused.

Try looking at it through a loupe, instead of a scope. You can maneuver the coin better and even hold it at an angle. The incused letters might be easier to discern.

Raised devices and incuse devices, all the rules change. On raised devices, the lines can flow behind the devices because they are die scratches. Incuse marks on the tops of devices are damage that happened to the coin after it was struck. On incuse (sunken devices), the letters are deep into the coin. The damage on the top of the coin can leave lines that makes it appear that is is behind the devices. But are on the surface of the coin. Just the opposite as raised devices. Machine Doubling and a doubled dies: On raised devices, Machine Doubling reduces the size of the devices. On a doubled die, the devices are enlarged. On incuse devices: Machine Doubling enlarges the devices.  On central doubled dies of these incuse devices they are reduced in size. Just the opposite happens.    So they are opposite on raised and incuse devices. |

I am wrong. I thought EPU were raised, never realized they were sunken in. Learn something new every day
