1974 D LMC Is This RPM And DDO And The Tie Is Weird

Your coin is the large date for 1974 (yes, there were a large and small date that year)
Proof small and large dates:


Business strike Small and large dates:

The Liberty area is showing the MD the strongest. Only one side of the devices are affected. Look at the centers of the devices, not the edges.

Added:
I forgot the question about the tie looking weird. That is form die over polishing to remove damage to the die or clash marks. Some dies get abraded so much that the devices start to go away. What does that mean? When a die is polished what goes away first? the fields. The outside part of a die is the fields. Thus when the die are handled, they may bump into each other. This may put a die dent, or get a scratch on the field called a die gouge or when being polished, the dies may show die scratches. Anything like a dent, gouge or a scratch on the die is a negative mark on the die. When it returned to usage, the incuse mark on the die, leaves a raised mark on the coins struck. But if the die is continued to be worked over with more polishing, the fields thin and the sub level devices that are sunk into the die suffers. Like your coin so much of the field was removed that the tie now looks, as you put it weird. But what happens when this is done many more times. It will start to look like this:

More of the sub devices, and now the mid devices are being removed. Thus the not neck look happens the mouth goes away, the bridge of the nose goes away and the die is reaching retirement soon because of was abraded so much. That is what happened to the tie.

Not a problem. Just keeping my gray matter active.
