Is This Machine Doubling Or Is This A Doubled Die 2020 D Penny?

Yes. None of the devices are enlarged. all the devices are all affected on the obverse on the same size. On the reverse, If you look at the tops of the EPU on the tops, you will see the enlarging of the devices, but on incuse devices, that is just Machine Doubling also. Also the left side of the shield is also showing the same MD there as well. Look for the devices that are enlarged larger than normal. Or distorted in shape. That is how you can tell if they are doubled dies. We see less of the notching and more Machine Doubling on the current coins.
The Liberty devices on these listing are not real strong, but these are the DDO-001-003
