Washington Quarter DDO or DDD

[junglistOn1]

Hello, This is a 1990 D Washington Quarter, that I think has doubling on the IGWT, but it may be just Die Deterioration Doubling. This is only on the IGWT and no where else. Thanks for the help.

It looks to me to be mechanical doubling, flat shelving

This is die deterioration doubling. There is no flat shelving, only a bulbous extension of each letter.

These can be very tricky sometimes to a inexperiance error collector to attribute.The coin has die deterioration doubling.

When looking at this coin you would think it may be a doubled die but it;s not. The T looks like it has notching but by looking at the letters they all have a mushy apperance and that ;s the dead give away that;s it;s DDD.

Not to be argumentive, but how can you explain the cause for this die deterioration doubling forming on the inner edges of the design element which is toward the center of the coin.

I may be wrong, but I was under the impression that die deterioration doubling was cause by cold metal flow and the erosion of the die surface by this action during the strike. Since the metal flow is outward from the center of the planchet, there is no cause for erosion on this die in the place that it is happening. Just my thoughts.

Die deterioration doubling can take on a wide range of appearances. It's common for DDD to completely surround a letter, which also conficts with any notion of outward metal flow. In my experience, the positioning and directionality of die deterioration doubling is rather unpredictable. It seems to be only loosely connected to any pattern of radial flow that is present in the field.
