Good afternoon everyone!! Hope you all are doing well!!
arby96 and Dearborn thank you for come and see my thread and give your opinions, always appreciate it.

Hope Tanman2001 give the answer to your question about whether this coin is
DDR or MD, I also am uploading some images with arrows pointing where the notch and spread are in this coin, I hope you can see it.
Thank you Tanman2001 for your explanation, I thought the doubling was just in the initial RG, E-Pluribus and the big E that is next but, but thanks to your explanation I checked the images very well again, now I can see that ther are also noticeable notching on unum and I believe on some of the letters of Unite States Of America too, not easy to spot in USA but happy to know there are some notching there.

Thank you jbuck, Petespockets55 and mb560600!!

yes mb560600 I believe those are die chips, apart of that I see two another marks that will be very helpful, I pointed them in this images
