1982 Zinc Penny DDR?

Your coin is a large date that appears to me to be a victim of MD.

I think you take some pretty nice pictures. Some of the devices were Struck Through Grease. I also think you should expand your horizons from only collecting 82's and 83's, either way though, I hope you find an 83 that weighs 3.11 gr.

Edited after reading Coop's post: Extra movement at the strike altered the devices, reducing them with the flat shelf-like portions. Machine Doubling

It is showing what I mean about the reducing the devices. When looking at your coin you see the area on the right side of the devices on the USA? The area that you see is an altered device. The normal overall size of the device is there, but because of machine movement of the dies, the right side of the devices are pushed to the left. Note on the "M" on AMERICA. The center part of the cross bar to the right, you can see where that are is reduced in size. The over all size is that whole area, but because of the die movement, it is now reduced.
Here is an example of medium hub doubling:

Can you see where the second hubbing was towards the center? Note the tops of the devices how they are taller and you can see notches on these devices. Note the overall width of the devices? The is the width that should be present on your coin.
Here is another one that is a doubled die , that is a light spread on the similar devices:

Note how the spread is not at strong toward the center on this one?


Here is a triple die on the same area:


Note that the notching is not flattened? The area is rounded, just like the original devices should be, but there are two notches in the spread.
Here is another one that the tops of the devices are affected on the TED area:

This one has a bit of die wear starting to weaken these devices, but again, note the hub doubling is rounded and not flattened reducing the devices, but enlarging the devices. In this case make the device taller.
Another one that you can see the same thing one, but note the roundness of these devices:

Machine Doubling pushes, altering the device make it look step like. Now, go back to your images above and note what I'm talking about. On your coin you see the devices pushed to the left. squared and the are where altered is just one color in that area. (indicating that it is flat and not rounded. Again look back at the doubled dies I posted, the light shows a light to dar color because they around rounded and not flat. That is the difference.
On Machine Doubling the die is normal, the strike causes the difference.
On a hub doubled die, the devices are doubled because of the hubbing misalignment. so the doubling is on the die, thus the term "Doubled Die." It is harder to find doubled dies, but there are many machine damaged coins out there. Hope this helps. If not ask another question.

They are the same thing. I prefer to call it what it is: Machine damaged. nothing is doubled, from the damage that happens it is actually a reduction of the device leaving part of the device (bottom) not altered.

So I call them what they actually are. (I'm a realist)

Yes but it is different on the multi-hubbed dies and the single squeeze dies. On the Multi-hubbed dies the breakdown is more like die flow lines that flow from the devices.

Note at first the edge of the device nearest to the rim starts to wear down. Then it progresses to more distortion and even worse in VLDS it starts to break down even more. On the 1950's wheat cents (they were over used) you can see the enlarging towards the rim closest to the rim.

Notice on the tops of the devices on the motto how it is flowing towards the rim.
On the single squeeze dies there is a separation between the normal device and the Die Deterioration:

So they are different. They show up also a lot earlier because the devices and bust does not have as high a profile as the multi-hubbed dies. The single squeeze devices also seen to be wider than the multi-hubbed examples.

Very informative stuff
