I think it took a hit. The top and left of the mark are fat and normal, then the lower section is all bunched up and slid toward the center. The full outline is a normal punch, and then there was a strike that squished the bottom up into the middle. That's what it looks like to me.

On some mintmarks that get hit like your coin, the mintmark is taller than normal. So when the MD did a higher bounce, it missed the other devices, but the whole brunt was on the mintmark area. Thus why that is distorted on your coin. A high bounce of Machine Doubling flew over head of the other devices. How do I know that is the case? (Sherlock revealing a secret) Note the fine lines on that affected area? Those are striation lines. We see these when a sharp edge of the die affects an area on the coin. It is like the forensics of a knife blade used in determining an autopsy. These are seen on Machine Doubling lines. I call them striation lines. When I see this, I feel this is not a coin contact issue, but a die sliding issue. Other examples below.










On the last image you posted, it was the first case of full brunt contact of MD on a single device. Note how much stronger it is from the examples of full devices striation. Thanks for post that. Now I can keep on the watch for more of this happening. Not a premium for it, but more like the last piece I needed for my puzzle. Another coop secret revealed.

Coop, as always, your in-depth analysis is fantastic. My question this time around is, why wouldn't there be these striation lines on other parts of the coin. If the die is sliding, wouldn't there be other indications somewhere else? More specifically, in the bottom of the torch area or the lettering on the reverse?
