2021-D Lincoln Shield Cent Reverse Question

I'm still thinking these are more of a die polishing issue. If so they EPU should be weaker than a normal coins EPU. Try making a Side by side with a new Coin the same year and this EPU to see if they are weaker as not as deep on these devices. (These devices are incuse on the die, show any polishing the the die will weaken these raised devices on the die. So if you could provide a side by side it will help prove my point) Weakened would make them look wider/taller on these devices. (Just opposite of raised devices) Looking more like Machine Doubling on the a raised device coin.

I believe epu don't be weaker and skinny and distorted like we see on Philly ddrs.
Bc of the fact the only real time they are like is when the doubling is extreme either on the initials and usa.
This is in a different spot and not as dramtic so epu won't be affected and it's on a denver so you'll have different reulats

This doesn't happen all the time.
For instance on 2012 003 & 004 those involve the stripes no distortion or skinniness on EPU. Those r Philly as well.
And on 2018 D 1DR-001 coppercoins listing.
This is one of the only known with doubling on USA on a Denver's shield you can see the spilts on the letters and extra thickness. No distortion on EPU at all.
I don't know how to explain it but I know for a fact it won't happen here I just know it.
from experience and searching the shields. You won't see skinny of distorted EPU on these doubled dies they r even minor then the ones I mentioned. but I still like them in hand they r neat.
