Need Help With This 2020 Tall Grass Prairie Quarter

I see a combination of Machine Doubling and Die Deterioration. Note that the letters around the reverse of these newer quarters are incuse and not raised. True die doubling on incuse letters would actually make them thinner and would not show obvious notching or separation.

Thank you Tanman2001 for your view and expert eyes ... much Appreciated.

These devices are incuse. So any Machine Doubling will altered these devices that way. The real place to find DDR's is on the central areas of the design. None of these Machine Doubling examples are DDR's. They are very common. 70% of the time you can see mild to strong Machine Doubling on these quarters. They will never be listed, so don't fall for that. Center of the design on the reverses and earlobe/left side of motto is the areas for the obverse on the States/ATB quarters.

If these devices were closer to the center, then if they were a doubled die, they would be reduced in size, like the EPU on the shield quarters:



Note on the incuse devices, the hub doubling reduces the size of the devices. (Just the opposite for the raised devices)

On this area when Machine Doubling happens, it enlarges the devices:

So what happens with raised devices, incuse devices does just the opposite.
