Note the start that are affected are towards the rim, like we also see on the devices between the tops of the devices near the rim. That is die wear. Just like the heavy die flow on the fields making lines in the direction of the closest rim. What causes these? It the cause by the metal movement of the metal being shaped by the die over and over again and again. Same event happening during the strike. Causes wear on the dies after hundreds of thousands of strikes. It maybe a minor DDR or maybe a coin contact if that is the only one device showing this. If it were a stronger DDR, then the devices would be showing spread on them. Here is an example of the Philly DDR for that year. (I could find a Denver one that is on PCGS):
Note how the corners are affected on these devices. This is the strongest areas affected. But did you not the spread is going the same direction of on the devices even during the curve of the devices. Also note that the notches are on the center of the affected devices and not on the outside edges of the devices. This is because the the spread, or the distance is slightly different between two hub processes.
Here is the DDO-001 (Not saying this matches your coin, but the 'T' looked closer than DDO-005. The 005 is a QDO (Quad). If your Motto was that big, then you would have posted images of that area on your coin. How much doubling need to be present to be a match for a known die number? All of it has to match even angles have to match. I is not that die because something looks close.

CoopHome: How much of the doubling have to match in order to be from that listed die number? Does being close count?
