The images needs to be a lot larger on the areas you are try to show us. All I can see from the images is that it is a 1972 cent. We need to have a lot closer view of the EPU area.

Note on this one you can see he hub doubling on the tops of the devices. Also note that the devices are enlarged by the hub doubling.


This one is not as strong as the other example, so you will see notching on the corners of the devices. also the spread in the center of the devices is showing. (The spread is found enlarging the centers of the devices.


On this one there is a spread on the edges and center of the devices. Some may look at this and think that is it Machine Doubling. But that is not the case. Machine Doubling removes contour on the devices and leaves a flat shelf like look on the outside edges of the devices.

On this one example while it is a DDR, just not showing it on this area. But this is called flat field doubling on the left sides of the devices. As I mentioned this is not hub doubling. But it is from Machine Doubling on the first strike, that was flatten by the second strike. (Yes, second strike as all proof coins are struck twice, while business strike coins are only struck once.

Note the tops of the devices? Note the metal has been moved and pushed aside like pushed snow in the winter? Note the affected areas are 1. on the outside edges of the dies. 2. The contour was removed. 3. the affected area is now flatten and often reflect light causing glare on the Machine doubled areas. 4. This is not a doubled die issue, but a machine issue. So it is not a doubled die.

Same event as above, but on a business strike coin. The direction of die movement was different in this case.

Note on this example the tops of the devices was affected. I attribute this to Machine Doubling but calling it ejection doubling that causes the incuse mark on the tops of the devices when expelled from the chamber.

Another example of the same thing, but on the obverse. Just this area on the coin was affected.
So I hope this will help you see why it is important to have closer view images so we will see what you see on your coin.
