2020 Quarter D.d. I Believe

Incuse Machine Doubling presents the same way that doubled dies present on raised devices (extra thickness, split serifs, etc), while incuse doubled dies present the way Machine Doubling presents on raised devices (reduced size of devices).

There are no doubled dies on that area of the coin. Not one. These devices are incuse and when Machine Doubling happens (70% of the time on these) it alters the incuse devices by enlarging them. Just the opposite as raised devices. All the DDR's are on the central areas of the design. Skipping looking at these. They are a waste of time. (unless you like to have your hopes raised and then crash on the rocks on the shore. On these single squeeze dies, like on the EPU areas on on the cents, they are incuse devices. So what does a Doubled die look like on incuse devices. (remember I mentioned opposites?)



All the raised devices on this die shows the normal enlarging of the devices:


Because of this DDR, I figured out how the raised and incuse devices are different. Machine Doubling is enlarged by Machine Doubling:

So that is what your are seeing on your coin. Machine Doubling.
