Goldchic New Member United States 1 Posts	Posted 04/27/2022 12:53 am When Machine Doubling is created, is this a ONE coin event or are multiple coins doubled? I found one 2011 d Jefferson nickel with strong doubling on date and Liberty. Then I found another same doubling . Then another. Report this Post to the Staff

Dearborn Moderator United States 97511 Posts	Posted 04/27/2022 09:24 am with John1 MD is a die issue - the more it is used the more it wears out and the worse the Machine Doubling gets. So you will find many of these. 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 04/27/2022 3:13 pm The strike can be different from strike to strike. Here is an example: So depending on how loose the machine is, it doesn't always look exactly the same. Note the markers are the same on these images. So they are all from the same die. Just the MD is slightly different. Machine doubling doesn't make it a doubled die, a doubled die comes from the strike a doubled die.. So Machine Doubling can happen on a doubled die as it is a striking process, but the die makes it a doubled die, because of the doubled hub affect on the die not by the strike of the machine. CoopHome: What creates a doubled die? The machine post strike, or a doubled die? Can you have both on the same strike? Yes! Edited by coop 04/27/2022 3:17 pm Report this Post to the Staff
stoneman227 Pillar of the Community United States 2376 Posts	Posted 04/28/2022 12:06 pm Some varieties are known for being machine doubled. The 1939-S rpm-001 cent is one that comes to mind. I don't think that I have seen an example that isn't MD'ed. http://www.varietyvista.com/02a%20L...9SRPM001.htm Here is mine Report this Post to the Staff
