Looks like a whole lot of damage to me. Does Anyone see it differently? I wish we could see the whole coin not pieces.
Hard to tell I'm not good with the minor ones. http://www.varietyvista.com/01a LC Doubled Dies Vol 1/DDO 1946-D.htm http://www.varietyvista.com/01a LC Doubled Dies Vol 1/DDR 1946-D.htm
Looking for a minor doubled die, die erosion or machine doubling on a coin with this much circulation is not a productive use of your time. It's not even a good learning coin because it's hard to tell for sure what you have. Find an uncirculated example of stronger machine doubling and find an uncirculated example of stronger die erosion and keep them to refer to. You have a circulated cent...... move on and keep up the hunt.
Just looks like a circulated coin to me. But for the record, why did you think DDR? Why did you think DDD? Why did you think MD?
A well circulated, older cent. Thought I had posted this to you before, but evidently not, so here it is: For the best results, you should post "in focus," FULL IMAGE photos (after you upload your photo, two buttons appear: Thumbnail and Full Image, click Full Image and your photo appears full size on your post and are easily enlarged by clicking on it). Photograph coins on neutral backgrounds like black, grey, or white. Crop out superfluous background so just the coin shows (you can use https://www.remove.bg for free), and post photos with correct orientation so members don't have to turn their computer in some awkward fashion to view it properly. While it isn’t always necessary, it is nice to show both the obverse and reverse, even if your question is just about one side. Members can often give more valuable information having both sides to evaluate. Add close ups of areas you have questions about and make your questions as definitive as possible so we know what you are asking for. And try to have the best lighting possible to show the most favorable photo of the coin. Hope this helps in the future. Good luck.
