It looks to me that I may have finally found a double-die coin, but I keep getting tricked by common shelving. Please have a look and let me know what you think. I see it only on the obverse.

Thanks!

It looks like Die Deterioration Doubling caused by a worn die along with possibly MD. It is not a DD.

with above.
Take a good look at the R in Quarter - notice how the back uptight of the R is skinnier than the rest - and it is shelf like - that is MD.
There is also radial flow lines on the fields that tell me it is also DDD.

Yes, a stew of Machine Doubling, seasoned with Die Deterioration.

The die state is a later die state example. Judging by the extreme flow lines this one was on it's third polishing because the raised devices are starting to loose their shape.
What you are looking at on the devices is Machine Doubling. So this is an extreme die wear example. This is not DDD as the die creation of the DDD is the single squeeze dies. So it is not DDD. This is the old fashioned multi hub die process. The single squeeze dies show the die wear on the fields first. On these dies the outside edge towards the rim, are affected first. So this is just die wear, not DDD. Both are wear, but the die wear patterns are different. Also the profile heights are different. The single squeeze dies have the lower profile. The old fashioned multi hub dies have the higher profile. (Thus I feel why the fields are affected first on the single squeeze dies with the DDD)

Die wear on a normal die with Machine Doubling is you are seeing on your coin. If this were a DDR, then the devices would be enlarged:

Note on the top image, this is a normal die example. On the lower example it is a DDR. That is how much of a difference a strong DDR will enlarge the devices. Not the spread? That is what to look for on a doubled die. Look at the centers of the devices, not on the outside edges of the devices. The outside edges is where you will find Machine Doubling and die wear. So when looking at the devices, look at the centers of the devices. No spread there? Move on to the next coin. To continue looking will find you what you found on your coin. Not a doubled die.

Wow! OK, that was a huge amount of great information. Sorry not to have the DDR, but gained some knowledge today. Thanks so much!
