This is a normal die. Note the devices are not widened like
DDO would look like. The die on your coin is aging, and the
DDD is just starting to appear on the devices closest to the rim. So next to the rim we see die wear. On the EPU on the bottoms, that is
Machine Doubling. Just like acne, they can be a mild or extra case. Yours is just a normal die coin with slight
Machine Doubling. What area you need to work on is to not look at the edges of the devices. That is where you will find die wear or
Machine Doubling. On a doubled die the devices are enlarged on the centers of the devices:


This one is a side by side for the Denver
DDO, but the principles are the same:





Note on the
DDO, the devices are often wider/taller depending on where they are located on the coin. The normal size is even reduced by
Machine Doubling on these affected areas. So don't look at the outside edges of the devices, look at the centers of the devices to see if they are enlarged or not. If not, move onto the next coin and don't look at the inside/outside edges of devices. If you keep looking, you will find the
Machine Doubling. What is the difference. A double die looks that way because of the die creation process. On
Machine Doubling the machine creates the doubling after the strike. On a doubled die the opposite side is usually normal, but on
Machine Doubling you can see if often on both sides of the coin.
