Dearborn Moderator United States 95982 Posts	Posted 04/20/2021 12:42 pm nice specimen there, it looks like MD to me, but then I'm still trying to learn to pick up on these types of errors. So, with that said, the Experts are here somewhere and you may get your answer.. Collecting since 1972. Learning from then on "Tell me and I forget. Teach me and I remember.

coop Bedrock of the Community United States 62064 Posts	Posted 04/20/2021 1:30 pm The close up images are perfect. But now for the bad news, that is Machine Doubling, not a doubled die. The clues for Machine Doubling is this: 1. MD affects the outside edges of the devices. 2. The areas affected are flat, not rounded like the normal contour of devices. 3. The are flat looking shelf like. 4. The are very common. It is the machine that is affecting the coin. Even doubled dies can be affected by Machine Doubling. Why? Because as I mentioned, they are affected by the machine. So a normal die and a doubled die can show evidence of the type of after strike damage to the devices. 5. The affected areas that draw attention, are a reduction of the devices. On a doubled die, the devices are enlarged on the raised devices and reduced only on incuse devices. (Yes, on incuse devices, the rules are opposite. On the incuse devices, the devices are enlarged by Machine Doubling. Just opposite of raised devices.) CoopHome: How it Machine Doubling seen on coins? Well the rules might surprise you? Report this Post to the Staff
