Doubling is a hard word to rhyme with. (Troubling is the only word that I can think of that would rhyme?) Machine Doubling
always removes part of the contour on the devices. A doubled die is not flat/90 degree looking on the devices. They show spread from the hub enlarging the devices. Note on your coin the areas affect on DIME are showing a push of metal from a slight bounce of the machine after the strike. Note how the I'm on Dime is showing s push upwards those devices. Machine Doubling
is from a slight movement of the die on normal or on doubled die die coins. Machine Doubling
is never die doubling, but alteration of the devices post strike. Like pushed snow the metal is move and the contour is removed on that area. Leave a 90 angle push into the device. On your coin you can see the rise of metal from the push. On a doubled die the metal is enlarged in size because the exact alignment of the hub was different slightly during die creation. The more the spread, the wider the devices will be. Note on the V.V site for this yearLhttp://www.varietyvista.com/07%20Ro...1PDDR001.htm
Note on the DDR-001
: for that year. The Description says:
Description: Medium spread on UNITED and ST of STATES.
The key word is medium. That it is very minor on the die, thus the coin only shows some areas affected.http://www.varietyvista.com/07%20Ro...1PDDR011.htm
Note on the DDR-011
Description: Strong spread on UNITED STATES OF AMERICA, ONE DIME, and E PLURIBUS UNUM, both stems, and lower torch.
Note the key word. Strong. This DDR
is a lot stronger showing spread. But on these examples the areas affected are not pushed showing a 90 degree angle. When you see that it is Machine Doubling
. This can happen on a normal die or on a doubled die. The Machine Doubling
is not part of the doubled die. Only the hub doubling is the doubled die. So you can a die issue and a machine issue or just a doubled die without Machine Doubling
. Machine Doubling
doesn't make a doubled die. Machine Doubling
can vary from strike to strike. While hub doubling is the same on all coins struck with that die. Hope this helps. If not, ask more questions. Always glad to help you see what I see on your coin. CoopHome
: Does Machine Doubling create a doubled die?
no. it is a doubled die only if it comes from a doubled die. Machine Doubling
never creates a doubled. you can a doubled die with Machine Doubling
. but Machine Doubling
never makes it a doubled die. the difference? doubled dies create doubled die coins. Machine Doubling
alters normal and doubled die coins.
