Fes_canon New Member United States 16 Posts	Posted 10/12/2025 02:01 am I was going through my coins and remembered that 1970 is a key date. So I gave it a harder look and found what looks to be doubling on the date and maybe the mint mark. I would appreciate more experienced eyes than mine. Thank You. Report this Post to the Staff

JimmyD Bedrock of the Community Canada 21630 Posts	Posted 10/12/2025 07:21 am I agree with Machine/Mechanical Doubling. You can't have a DDO on the mint mark as it is hand punched. Edited by JimmyD 10/12/2025 07:21 am Report this Post to the Staff
ijn1944 Bedrock of the Community United States 19201 Posts	Posted 10/12/2025 08:13 am Yes, a good example of machine doubling--flat and shelf-like. The '69 S and '70 S memorial cents are known for this. Report this Post to the Staff

FsdWarp10 Pillar of the Community United States 688 Posts	Posted 10/12/2025 4:21 pm Most of the time on cents with hand punched mint marks it will likely be Machine Doubling when both the mint mark and date are doubled in this manner. Report this Post to the Staff
