mb560600 Valued Member United States 367 Posts	Posted 06/29/2026 9:49 pm Got this from my bank today. There is obvious doubling on the lower reverse lettering, particularly HALF DOLLAR. Also doubling of the Eagle's left lower tail feathers, along with thickening of all of the lower stars. I checked Variety Vista and there are six DDR listings for 1971-D--- but none look like this. Possible new DDR? Thanks for taking a look and for your comments. Report this Post to the Staff

Dearborn Moderator United States 97930 Posts	Posted 06/29/2026 10:52 pm I see Machine Doubling mostly, and a bit of DDD Collecting since 1972. Learning from then on "Tell me and I forget.

Earle42 Bedrock of the Community United States 10047 Posts	Posted 06/30/2026 6:43 pm Anytime you think you have a doubled die., go to varietyvista.com and find an EXACT match. If you do not find an EXACT match (every picture per entry shown must match), then you have a non-collectible form of cdoubling like Machine Doubling or Die Deterioration Doubling.
