Frank Baumann Valued Member United States 451 Posts	Posted 07/07/2023 6:37 pm Hi, It is Machine Doubling / MDDR not a true doubled die. Report this Post to the Staff
Brandmeister Pillar of the Community United States 6493 Posts	Posted 07/07/2023 6:45 pm Stony, there are a few great resources for determining the difference between Machine Doubling and a true doubled die. The first MD article is Coop's guide, found by clicking the Machine Doubling link right here. His guide is huge but it has a lot of pictures. The other MD resource is Error-Ref.com: https://www.error-ref.com/?s=Machine+doubling+ The best two comprehensive sites for true doubled die coins are Variety Vista and Wexler's guides. Both guides are pretty huge, and can be intimidating to rookies. http://www.varietyvista.com/ https://doubleddie.com/ I also happen to really like the NGC Variety Plus site. They are a third party grading platform. They only cover the most popular and clear cut variety coins, and their site also includes a price guide. You can also look up prices on PCGS, but you have to know what specifically you are looking for first. Which is why I prefer NGC VarietyPlus: https://www.ngccoin.com/variety-plu...ited-states/ Report this Post to the Staff

Brandmeister Pillar of the Community United States 6493 Posts	Posted 07/07/2023 7:45 pm Alongside the M in America, looks like some push doubling cut into the right side. Report this Post to the Staff
Errers and Varietys Bedrock of the Community United States 73931 Posts	Posted 07/07/2023 8:16 pm I agree. It's Machine Doubling. Errers and Varietys. Report this Post to the Staff
