The strike was from a normal die. After the strike the devices were altered on the coin in a milla-second. So why is the not a doubled die. The normal strike happened, the Machine Doubling
happened, from a normal die. If it were a doubled die, the devices would be enlarged, by the die because of the doubling on the the die. Thus the term doubled die. But on your coin the machine caused the Machine Doubling
that reduced the normal size of the devices. Here is a three way view. Machine doubled, normal device and a doubled die:
Note how the MD reduces the over all size of the normal device? Then note the two images on the right side. Normal and the doubled die. The devices are doubled, because the doubling is on the die, not caused by the machine. A doubled die happens on every strike, because the doubling is on the die. But a doubled die can experience Machine Doubling
also. So Machine Doubling
is common. Caused by the machine. It is not a doubled die.
