lovinthecoins913 New Member United States 36 Posts	Posted 05/20/2022 09:46 am Going through a roll of uncirculated 1968S and I'm finding many coins like showing in the photographs. Hopefully the photographs are good enough for viewing. Are these of the double die varieties? Report this Post to the Staff

lovinthecoins913 New Member United States 36 Posts	Posted 05/20/2022 2:19 pm Dearborn, the MM appears doubled to me. I'm not sure if it would be called a RPM or not. So, would you say that Machine Doubling is worth much of nothing? Report this Post to the Staff
lovinthecoins913 New Member United States 36 Posts	Posted 05/20/2022 2:22 pm Dearborn, a lot of these coins have chips inside the curls of the S mint mark... I'm figuring that it's just normal and not a clear S mint mark. Report this Post to the Staff
Cujohn Pillar of the Community United States 7174 Posts	Posted 05/20/2022 6:03 pm I see MD all around and no RPM. MD is not a premium. Report this Post to the Staff
coop Bedrock of the Community United States 62064 Posts	Posted 05/20/2022 8:02 pm Very common medium bounce Machine Doubling issue. Very common on 1968-1972. A doubled die can have Machine Doubling, but Machine Doubling never makes a doubled die. A doubled die is created only on a die that have hub doubling on the die. Report this Post to the Staff
lovinthecoins913 New Member United States 36 Posts	Posted 05/21/2022 3:08 pm Coop,those are some nice images you provided. What the heck is a double die than? If Machine Doubling is not a double die than what's a double die. I'm guessing the only true examples are the 1969S and 1955 Lincoln's. I thought I knew the differences but I'm sad to say that I do not. Report this Post to the Staff
Cujohn Pillar of the Community United States 7174 Posts	Posted 05/21/2022 5:27 pm As coop says a doubled die is when the die imprint is doubled. Machine Doubling is when the die either moves or the planchet moves during the strike. Report this Post to the Staff
