Could be from over polishing that area resulting in the devices are not as tall and wider.

The weakness on States ic common. The opposite side of the bust is getting full metal from the planchet, but the reverse suffers. The devices on a doubled die will be enlarged fully. Note on the weakness, the full height is missing. So as mentioned earlier, that area didn't get the full metal there. If the planchet is even slightly lite, that area will not have the full strike up on those devices.

So, if I read correctly, the larger D STA is from Die Deterioration or over polishing, correct?

No that's hub doubling on the die. That is called "spread ".

I'm sorry Coop, I meant from my picture here... what causes the top coin to have a wider and longer D ST than the bottom coin? Both are same year, mint etc... Are you saying that is hub doubling?

When comparing coins,you need to use the same date and same mint mark as well as same condition. John1

Thanks John1. Unfortunately, I only have one copper philly sd so I am comparing it to a zinc philly sd. But still, the D ST are longer and wider than the surrounding letters on the same coin. What is this error/variety called or what causes the letters to be fatter and longer, but not as thick as other letters? I've looked through all the comparison photos I can find here, DD, copper coins, variety vista and error-ref, and the only reference I can find to this type of lettering has been on other coins listed as DDR. I'm sure, I'm not that lucky, but I'd like to figure out what I'm looking at and why it's the way it is. Is there anywhere else you'd suggest I try? Thanks again.

You covered all the reference sites but Wexler. I do not think you will find your coin on any of those sites because it is not an error or variety,IMHO. It is a known areas for weakness during the striking process and sometimes has a Struck Through Grease issue in the same area. Along with circulation wear/flattening. John1

John1 is correct. that area of the die had a Struck Through Grease error. It is often we see weakness on this area where the metal flow was not sufficient to fill out all the devices:  But I ruled that out as the rest of the devices are present, but the Grease Fill prevented the full strike on some devices on that area. But this widening of the devices is just removing the narrow part of the devices from being seen. On a doubled die, we see even the base of the devices enlarged and doubled on this DDO.  Note the 'E'? Your coin is from a regular die. Note the outside width of the stacked coins, are showing the same base width on your images devices?   Note the 'A' and the "E PLU" Devices? See the doubling. Your coin is not showing that. On a match for a doubled die, it has to match all the devices. If not, then it is not that die number.

WOW!!! Awesome!! Thank You John1 and Coop!!! If I haven't said it before, thank you so much for sharing your knowledge! There is a steep learning curve to these designs, and while they become more clear daily, I'd be completely lost without the effort you all put in here. Thanks again!

Well that is my personal goal. I want yo be able to show you what I see on your coin. When I was trained, I was give yes or not answers. Nothing else. What took me many years to learn, I'm getting the new ones here to feel comfortable in months. I also try to train the others the advantage of this hands on program so when I'm not here, they too may help out.

And years it must take!! I can't tell you how many times I wax absolutely sure what I was looking at was die doubling, only to see nothing attributed, or nothing that looks like whatever I was looking at!!
