1. Note how it reduces the normal size of the devices.
2. The affected areas are always lower than the devices.
3. They are flat and shelf like. If the coin is BU, the when light hits these areas, it creates glare. This will be seen from you angle, but on images it will look something like this:
On this inverted color image, the glare is removed and then we can see the Machine Doubling.
4. Machine Doubling affects the outside edges of devices. A doubled die shows a spread on centers of devices.
5. A doubled die has the doubling on the die. Machine Doubling alters the strike right after it strike is through. Damaging the devices. On a doubled die, the Machine Doubling can also be seen:
Note on this image, the date digits are all hub doubled. Then note the yellow arrows? Note the outside edges of the same areas on all 4 coins are affected in the same direction, but not all exactly the same.
6. Machine Doubling is common and happens a lot more than you seeing hub doubling. So no premium for Machine Doubling, but on a die variety, it doesn't cancel the die variety, it is now just a die variety with Machine Doubling. (Something that die variety collects don't want)
