MSI2 Valued Member United States 223 Posts	Posted 06/27/2017 1:20 pm I found this 1972-P LMC several days ago. I have been on the fence as tp whether it's a real DDO or just another coin with MD. It's most likely MD but I don't want to throw the baby out with the bath water, So I decided to ask all of you for help. All input greatly appreciated. Report this Post to the Staff

MSI2 Valued Member United States 223 Posts	Posted 06/27/2017 2:18 pm Thank you guys for the input. I'm a little fuzzy on Master die doubling. The master die is used to make the working dies correct? Since the doubling I observed originated from the Master die the doubling on the coin is considered normal and not an error/variety correct? Report this Post to the Staff

I believe not all 1972 show the master die doubling as more than one master die is created. All working hubs created from the one affected master die will show it, which in turn transfers it to the working dies made from the affected working hubs. See hierarchy below. If the master hub was affected, then it trickles all the way down. Thanks, Doug. Image from coops library. http://goccf.com/t/262295 Edited by Halo1st 06/27/2017 5:13 pm Report this Post to the Staff
Crazyb0 Rest in Peace 10197 Posts	Posted 06/27/2017 6:25 pm Halo1st, Good point. May not have all this completely down but this is a close description...Per your diagram notice generally one die is made as the master Hub. This die then "Imprints" a group of Master dies. Note the hub dies are "positive", meaning reversed image from one to the other. Master die Doubling happens in this process, affect one or more dies. The working hub dies produced will then may have clear or error images when producing (imprinting) that working die. A bit more is involved, but that is why one or two mints may have the same master die doubling as the working dies become distributed. Report this Post to the Staff
