Flippincoins0 New Member United States 30 Posts	Posted 01/29/2023 08:15 am After further review...A closer look shows a lot of similarities between mine and Variety-002 on Variety Vista. I was also informed that Machine Doubling is not frequent on copper pennies as it is on zinc. Report this Post to the Staff

Dearborn Moderator United States 98440 Posts	Posted 01/29/2023 08:46 am Quote: I was also informed that Machine Doubling is not frequent on copper pennies as it is on zinc. Where did you come across this information? can you post up a reference to this info please? I'm fairly sure that MD is relevant on all coins of all denominations of all years. Now I read here on CCF (possibly from Coop) that there is something that only occurs on zinc coins but can't remember at the moment what it is (I'm not thinking zinc rot, bubbles, or plating issues - that is obvious).

coop Bedrock of the Community United States 62064 Posts	Posted 01/29/2023 2:06 pm It happens on any coin that is struck. The movement of a looks machine damages the fresh struck devices an alters them. It can be different on each coin as well. Found in rolls from the same batch. Note the same marker and the strike was different on each example posted here. So depending on how loose the machine is, it damages the coin when rising off the strike. Sometimes mild, sometimes crazy: When the coin is damaged, the affected area will be incuse and have a 90 degree angle on the affected area. Just an alteration on normal and doubled dies. But only a doubled die, can create a doubled die coin. Machine Doubling never creates a doubled die, only a doubled die can create a doubled die coin. The Machine Doubling is never part of a doubled die. On the 1968-1972 cents it is very common to see this on the cents. Larger denominations often have altered devices on them. On a doubled die, the devices will be wider/taller. Sometimes even showing a large spread: Spread. Report this Post to the Staff
nickelsearcher Moderator United States 15555 Posts	Posted 01/30/2023 05:53 am Agreed - its simply Machine Doubling. Take a look at my other hobby ... http://www.jk-dk.art Report this Post to the Staff
