Hello everyone, I am an italian collector, while browsing in my grandfather coins I found few dimes. One of these presents signs of possible mint errors. I have absolutely no experience in identifying these, expecially on american coins.
Please let me know what you think so that I can learn something new!
The flat, shelf-like doubling you see is, like Coop said, Machine Doubling. O ther "doubling" I see in the pictures is the result of the lighting used interacting with whatever magnification and camera you are using.
Thanks, after posting I read Coop's link and I think I understand how it happens. My only doubt was on the "in god we trust" that was different than the rest. Do you think I should scrap it for silver or has some kind of numismatic value? Thanks. A.
You are concentrating on the edges of the devices. On a doubled die the centers of the devices are enlarged:
Note the spread on this DDO? Where is it. Its not on the edges of the devices, it is on the centers of the devices:
Note on the next two sets of images, the DDO is not as strong as other areas of the doubling. These areas show less/little spread. This is common on a stronger doubled die. Because the hub was more correct on alignment/or not hub distorted to create one area stronger and others weaker. The class one with the rotations of the hubbing show the doubled dies better.
Note how much wider than normal these devices are? Where is the spread? On the center area of the devices.
Note again the doubling is not on the outside edges of the devices, but on the centers of the devices. Hopefully seeing more examples will help. Keep in mind that the Motto on Dimes and Quarters distort a lot, as the die ages.
