Anyone recognize this planchet size?

I came across this dime in a collection of dimes that had been set aside for quite awhile until I had time to research. Now that I am retired, figured it was about time. It is a 1983 D Roosevelt Dime on an offsized planchet. The diameter is 16.72mm with a well formed very symetrical rim and no reeding. The weight is only 2.0 gr. The color is off as well, medium grey and has no luster, but is very sharp in its detail.
I have been looking for potential foreign planchets and have not found an exact match; some close, but not matching both.
Any thoughts are welcome.

  • Thanks for the quick response. Here's a picture.

  • Normal weight is 2.5 gr and this one is only 2.0. Pretty significant difference (20% less). Then there's the 6.5% difference in size. Here's the back photo.

  • Thank you Fred. Sorry for what may be a silly question on your response, I do not recognize the acronym PMD. Can it really loose 20% in a dryer? Are we talking a home clothes dryer? I have put lots of coins through the wash before (much to my wife's delight! Our agreement is she gets to keep anything she finds in the wash) and they have never shrunk because of it.

  • Thank you all so much for the valuable information. I was not aware of that mechanism on wearing down the rim. I was having a lot of difficulty understanding how the rim that is there exists with the coin detail inside the rim. It still seems a bit of a miracle that the rim is so uniform.
    One last question, since this is Post Mint Damage, is there any value to this coin? any points for uniqueness?

    Look at the design. It was properly struck up before it was damaged. The rims push/fold against the design. It was worn down in dimension after it left the mint.

    Unfortunately not. But please stick around the forums. It’s a great place to learn and share.

    I just think the degree that the "3" in 1983 is buried in the rim is to an unusual degree.

    Great transactions with oih82w8, JasonGaming, Moose1913.

    Keep the coin as an example of the 'problem'...PMD comes in many forms and this type is more common than most people think...Cheers, RickO
