Need Some Help With This 2015 Roosevelt Dime

My initial reaction is we're looking at rather severe case of Die Deterioration.

Dang, thought I had something with this one, but my pics don't do it justice! The 2 in the date almost looks like it was struck in the middle of a much larger, smoother, less defined 2? Is it common for DDD to leave the ring around the edges of coin, that appears "rough" on both sides? Again my pics aren't showing the full effects of him, or the lettering from "STATES" that can be seen under the bust, in fact I didn't see at first, but under magnification, I could see straight lines and 90° angles, then could make out a T and an A, then told myself "if I turn over and there's a T or A on the reverse at that particular spot, it must be lettering"!! Sure enough, STATES is located under same location on the reverse

Everyone is considering the final outcome on this one. True it is DDD, die flow lines on the fields. But an die event happened before this happened. Clues:
1. Note the reverse. Note how the center of the design is not showing fie flow lines. So a die polishing happened.
2. This die polishing caused the devices to be altered. what even could cause this?
3. The cause was Feeder Finger Damage. When the fingers scratched the die, they rescued this die by a sever polishing so they could get a few more strikes out of the die before die retirement.
We see this on the dimes. Keep in mind the die polishing that removed the center of the reverse. It was to remove the Feeder Finger Damage:

Thus the flat behind the rear devices. So the damage appears to be stronger on the reverse. But also the obverse was also polished. So the weakness of the polishing affected the devices making them shorter in height and weaker/smaller in size. That is the cause, before the Die Deterioration lines, since that polishing. Cause and affect. Thus when the FFD happened, it was the beginning of the end for this die. The rescue allowed the die to be able to continue for a while longer. But the Feeder Finger Damage was the first event. The die polishing the second die event and the die wear coming the die flow is the third die event. That is what we are seeing on this coin. It happens several times, but probably not often. Before the first cause to the die, the Feeder fingers were struck with the dies, altering the shape of them, thus they started scratching the dies with each strike.



Sometimes the fingers break off and they look like a coin, but are not made from the stock material, but actually are part of the Feeder Finger Material:


Remember on mechanical things, cause and affect. That is what happened to this dime.


Note on the above image, it shows how the dime obverse is affected with Feeder Finger Damage.

Cause and affect. The polishing affects a small area, the polishing on the fields affect a larger area. Thus the weakness of the lower obverse die devices. The stronger the damage the more field metal is polished off.


CoopHome: Why do some dimes look strange on the single squeeze dies design? What is cause and affect? Another piece of the puzzle revealed.

Self taught. I dig in deep on some subjects, dealing with images provided here and and considering cause and affect on the dies, striking process, what can and could happen. Again Cause and affect.

Well you never get to know everything, as new things are discovered all the time. I started collecting in 1964, quit for a while when I was raising kids. Then started back again in the mid 1990's Been figuring out things from since then. I started getting real serious. Most of what I was taught was yes or no answers. No reasoning. So what took me many years to know, I teach others the quicker progress a lot faster. Doing this helps me think differently on how to answer question. If I stayed om the same rut, Some would not think deeper. So when I see the same answer over and over, I try to come up with a better way to explain what I see on their coin. Using different approaches helps others to grasp the idea quicker. Being a person that hates trying to learn from books and wavers that they send you, I take the use of images a lot better. When you can see it, then you understand it a lot better and helps memory retention. So since 1990 its been 25-30 years of saving images and learning more. I like a challenge, so I challenge myself to help others see what I see on their coin. Many have appreciated this method. A few months is better than many years of trying to figure it out yourself.
