Well I figured since we already had one going on the topic I could lend a hand w better pics. I am also wondering about the same thing as cananxhaves

Ahhhh I finally get it! Ok so in other words your saying it's under flow because the lettering#s are walloed out and adjustment is too high actually worn,?

Die flow is the lines you see on the fields that start in the center of the coin and slowly walk to the edge of the coin to meet the rim.
Die wear on the devices start on the devices that are closest to the rim direction. The constant movement of metal in the single direction, causes the die to wear on that area. Slowly it starts to show the device bigger looking on the areas farther from center of the die.



Eventually it gets even worse:

Note how the device enlarge and walk to the rim of the coin?
On your coin, the device are wider near the rim, but more normal looking farther from the rim.


Single squeeze dies in the VLDS die state enlarges the whole device:



Here is a circulated quarter with a strong DDO on the motto area"

Note despite the circulation wear you can still see the notching on the corners of the devices and also not the doubling is equal, not distorted like die wear causes. (Wider on the devices near the rim area, weaker on areas further away from the rim area)
