I can't see the serifs closely enough to know for sure, but I think that it is machine or Mechanical Doubling (MD), rather than a double die, but a nice coin regardless. |

I agree. Not a doubled die, but still a sharp looking coin!  |

Thanks for the comments! Now, wouldn't it be possible to have DDO with MD on this coin? I tried to take a better picture but the brightness of the coin makes it very difficult, and this is done with a 5 megapixel camera. What I got were these pictures, I focused on the D and the date. The number 1 at the bottom seems to have been damaged again, so it seems that its base is normal.        |

I see alot of reflections and shadows. Hard to tell without it in hand with a loupe.

Yes, it's a 1980 set.   |

No, it's still mechanical/machine doubling. Read the Wexler link that I pasted above and look at the examples further down in the article. It's still a neat coin, but just an error caused by the locks on the die coming loose and the planchet moves a little (microseconds) as the die rises up and off the planchet. Once the die is locked back in place the doubling stops.
