I have been searching through my coins I have collecting for many year but not had the time until recently to immerse myself in to the fun of "modern treasure hunting" with I am sharing with my nine year old. We can across the following coin and I think it may be a Machine Doubling but I am no expert... Do coins like this have any real like DDRs or similar or is it a neat find and I'll labelled it in our collection. Thank you in advance for any feedback on my learning journey!

Instead of reducing the size of the devices like regular Machine Doubling, it enlarges the incused devices in size. It's very common and carries no premium at all. https://www.error-ref.com/incused-m...ne-doubling/ Errers and Varietys. Report this Post to the Staff
