mikesnyd97 New Member United States 4 Posts	Posted 10/06/2021 9:49 pm Any thoughts? And can somebody answer two questions for me as concisely as they can because I am still having trouble understanding: 1. Can a coin have both Mechanical Doubling AND hub doubling? They are two seperate processes for how each is manifested so I don't see why they couldn't coincide together, though would be quite rare I'm assuming. 2. How could it be possible for a coin to have thicker letters than normal (meaning thicker density than another coin of the same year) and not be considered a doubled die? And let's assume that it's not Die Deterioration; has defined edges and does not sparse towards the edge as it would in Die Deterioration. These questions have made be quite unsure of a lot of coins I have (from my grandfather, who was a coin collector from the 40s-80s) in determining if they are DDO or not. And no one has been able to give me a clear, logical answer other than "It's MD" or "It's deterioration, PMD." To my understanding, MD is flat and has no impact on the thickness of the letters (correct me if I'm wrong) and Die Deterioration, I will say, can be a tricky one but still should be somewhat easily distinguishable from hub doubling. What am I missing here? Sidenote, don't take this 1982 to be one that I feel incredibly strongly as being DDO (though it does look like it to me), I don't feel as strongly about it as some other coins I have that I am still unsure about. Thank you in advance for those who are willing to take their time to help me, it is greatly appreciated! -Mike Edited by mikesnyd97 10/06/2021 9:52 pm Report this Post to the Staff

Yes, they can both be present on the same coin and can make it quite confusing to attribute. I've seen some posted, that messed with some of the best minds, because of this. There are lots of forms of MD and some are more deceptive than others. LINK http://www.error-ref.com/?s=machine+doubling Quote: 2.

Someone more learned than I will chime in but I cannot think of anything other than what you have mentioned that would cause thickness. I have a whole can of nothing but 82's that I have put aside to investigate further. More than likely, the majority of what I have are from deterioration though. The font used on the large date 82's was thicker to begin with, which does not help. The best way to determine if it is a doubled die, at least on the 82 you have posted, is to pay more attention to the distance between the letters and not so much to the letters themselves, there will be less field showing, than on a normal coin. -makecents- Report this Post to the Staff
coop Bedrock of the Community United States 62064 Posts	Posted 10/07/2021 3:34 pm But on your coin, it is a case of the aging master hub. That year they introduced a new creation of the master hub mid year. It turned out they ended up with a large and small date during the year. I though, "Could I back create what the new die would have looked like by spherising the new design to make it look like the swollen die it was getting rid of. And yes it worked: Note the distortion of the devices were very similar, (just not the added thickness of the large date examples) Note how the 'WE' was make thicker because the height was reduced? I know I have strange ideas, but at least I'm able to figure out how to do them. Edited by coop 10/07/2021 3:36 pm Report this Post to the Staff
merclover Bedrock of the Community United States 10635 Posts	Posted 10/07/2021 7:04 pm What are the differences between a doubled die and Machine Doubling? This is one of the asked questions we have had over the years here on CCF. Here is a link to a source that explains these difference and other types of doubling as well: http://www.lincolncentsonline.com/m...oubling.html The best advice I can furnish is this: Read as many resources as you can, here on CCF and elsewhere, and look at the differences. Like anything else, the more you explore, the more you'll understand. Bonne chance! to the CCF! Report this Post to the Staff

Correct, but the OP asked a question about them, and a little education never hurt anyone. Plus, how many new people here to CCF understand the differences? My link was for them too. I am a teacher; it's what I do! Report this Post to the Staff
