If you actually had a doubled die, the incuse devices would be narrowed. Report this Post to the Staff

Kloccwork419 Pillar of the Community United States 1359 Posts	Posted 05/05/2020 12:51 pm This isn't a Doubled Die. Its Machine Doubling. Its from a high bounce with a lateral shift. Mike Diamond explains it here: https://www.coinworld.com/news/us-c...-machin.html I really like that background on the first pic. Did you make that?

SamCoin Pillar of the Community United States 3237 Posts	Posted 05/05/2020 12:52 pm Read my explanation again, Eyez. The lettering you're pointing to is incuse, which means MD will widen the devices and can create notches and split serifs. An actual doubled die on incuse devices will thin the devices, since the devices are proud on the die itself, and hence doubling them removes material that should have been there.

coop Bedrock of the Community United States 62064 Posts	Posted 05/09/2020 11:03 pm When you see incuse, what Do you think of? Raised is above the fields and incuse is sunk below the fields. so if a die is a negative of a coin, the incuse devices are raised on the die. The raised devices on a coin are incuse on the die. So The opposite happens. On a doubled die on raised devices, the devices get enlarged. On incuse devices the opposite happens. On the EPU on cents these devices are incuse. So when Machine Doubling happens, what does it look like on the the coin? So on incuse devices on a doubled die, the devices would be actually reduced in size. Machine Doubling on incuse devices enlarge the devices. Just the opposite as raised devices. I have yet to see a DDR on these devices that are incuse on the outer ring. We probably won't unless the die was re-insterted during the hub process. Why do DDR's never occur on the outer ring? On the single squeeze dies the central area is where you find DDRs. On the outer ring, a DDR has not yet happened. What you are seeing is Machine Doubling. But guess what. About 70% of the time, you will see Machine Doubling on these outer ring of the ATB reverses. Whether mild or strong. I'm still wondering if we will someday find one, but like a mentioned, it is not supposed to happen. There was a strong reverse on the Philadelphia Proof that is a DDR, but as I mentioned it was re-inserted during the hub process. (making it a doubled die because it the hub was used twice which isn't supposed to happen. http://doubleddie.com/186364.html Take a look at WDDR-001 CoopHome : Why DDR's don't occur on ATB incuse devices Edited by coop 05/09/2020 11:04 pm Report this Post to the Staff
