New 1959 D Jefferson nickel D/D Variety or Mechanical Doubling?

[homer6679]

Found this last week while CRHing nickels. Looks like a D/D to the north. It does look pretty crisp and shelf like so I'm suspicious of mechanical doubling. "America" has some minor strike doubling as well as the top of Monticello, you should be able to see the last A in the photo of the mintmark.

In my opinion, If strike doubling exists on a coin, then be cautious on the rest of the coin.

Mint marks were added to the working dies by hand up to 1989 or so.from 1990 to present, there are no rpms made, they added the mintvmark to the master hub, eliminating there-punched mintmarks. The mint marks that were punched by hand were placed onto the working dies have slightly different locations for each working die. That is how most attributors figure out what die or type of die number it is.

The best way to confirm location is via a coin photo overlay. It allows some one to match up a few letters or part of a building to see if the mint mark is in the same area. Trik is to have both photos thecsame size.

You can try to see if there was a match in mint mark location at

that is a good point to make about seeing MD on a coin, be wary of it being on dates, mm and other devices.
