1982 Large Date Zink (Lmc) DDO?

Deadland your coin has machine or Strike Doubling along with Die Deterioration. I have found a couple like yours and none of the markers matched for the ddo-003, or ddo-004. Arrgh I know, these 82 zincs are a real pain and difficult to discern. Checkout doubledie.com and study the ddo-002 copper, the ddo-003 and 004 and you see the differences. Good eye though, I would keep that baby anyways.

As already mentioned, it is Machine Doubling. Machine Doubling reduces/flattens/turns a device into a step down when this happens. Very common.

When a coin is struck, die movement damages the devices. (just like your coin) I've have yet to see a doubled die that affects the outside edges of devices. The spread is more in the center. When a device is affected on the outside edge of the devices, it is Machine Doubling.

Note the coin example on the right side of these images. Note the area affected by MD? It is the outside edge of the bust. On the left you see the doubling away from the edge of the bust.
Here is the only example I can think of where a Lincoln Cent has altered devices near the outside edge of the bust:

Note again the affected areas are not on the outside edge of the bust? All doubling is internal on these areas. What doubled die is this:



So it one area on the outside of the bust is affected, chances are then other areas are also affected. Just like your coin. The difference?
On Machine Doubling, the die is normal and altered after the strike and can vary each strike.

On a doubled die, the doubling is on the die, thus each strike will show the same spread.

On a doubled die, it can also be affected by Machine Doubling, adding a altered area to the strike.

(Not a plus for the coin though. (well to me it's not)
