Pete2226 Pillar of the Community United States 3331 Posts	Posted 05/07/2013 4:38 pm What kind of doubling would this be on the date and MM? Is this a case of Die Deterioation Doubling (Die Wear)? Or perhaps Machine Doubling? And how would you tell the difference? I notice that the doubling seems to be NE. Thanks, Pete Report this Post to the Staff

Fuzzy317 Moderator United States 14463 Posts	Posted 05/07/2013 5:00 pm think I see either a die chip, or a RPM. The date looks fairly normal with a few hits of PMD. Report this Post to the Staff

Sudz Pillar of the Community United States 1572 Posts	Posted 05/07/2013 5:28 pm Is it fair to say that if the mint mark shows doubling along with the date and/or the motto and/or Liberty, it is usually Machine Doubling? Report this Post to the Staff
seal006 Pillar of the Community United States 1915 Posts	Posted 05/07/2013 5:33 pm The tell tale of Machine Doubling is notice how flat the doubling is, and how it takes away from the device in question. True doubling will be the same shape, not flat. Plus the device being doubled will not lose size, but rather gain in size. Plus it is my understanding that the mint mark was applied to the working dies, therefore a true doubled die would already exist on the die prior to the adding of the mint mark.

Sudz Pillar of the Community United States 1572 Posts	Posted 05/07/2013 5:52 pm Nice illustration, DaveH! That should be in a sticky under "Important Topics" with the title: "If you think you have a doubled-die coin, look here first... with a note on or under the illustration saying that Machine Doubling is common and hub doubling adds value. It is very informative for a visual learner like me. Thanks for posting it! Report this Post to the Staff

Dave H Pillar of the Community United States 1436 Posts	Posted 05/07/2013 9:16 pm I don't remember exactly where the drawing came from, but most likely here on the forum. I frequent quite a few coin-related sites... Didn't mean any offense to anyone and give due where it's due Report this Post to the Staff
