1948-D 10C obverse doubling, DDO?

[ryanrich]

I see what appears to be doubling on this 1948-D Roosevelt and was wondering what you all thought about it’s origin, either mechanical or hub doubling. The reverse I have similar suspicions about doubling as well as maybe the mintmark but this is my first coin post and first time using this USB microscope so I’ll start with these!


Doubling along top of LIBERTY towards rim. Light crack from rim to head @1:00.


The coin is in an NGC holder and guardhouse sleeve and is being photographed through these. The pictures I’ve attached are of some of the areas I could get the best photos of. Please let me know anything I can show better and any general thoughts or advice are all appreciated!

In my opinion, it looks lower, shelf like and the letters like a bit thinner in some areas. That tells me that it's more than likely worthless doubling, like machine damage. Plus the working die that struck this coin was not as new or sharp as it was so the working dies have a tendency to slip just a tad. It happens quite often to these minting presses since they operate faster than a jack hammer.

I often tell folks to check their handy dandy variety sites like :

They can give you an idea if that year and mintmark have any documented varieties. If none are listed, then the coin more than likely is something else. For example, it's been about 76 years for this coin and variety vista does not have anything listed for the 48D 10c. IF there are listings for a particular year, it's important to read the description, as it will let you know where the majority of the doubled die will be located.

Happy hunting.
