I got this coin in a recent large lot of customer-wrapped rolls I searched. This coin is fascinating and I have not found anything about it on JFK sites, CONECA, ebay or anywhere. I had a bunch of other 1991 P that were all normal looking.

This coin has very prominent tripling of the portrait of JFK, the nose is tripled, the front chin is tripled, the eye is tripled and the ear is tripled. Other parts of the portrait (the back of the head & hair) are normal. The date and mottos and all the reverse is normal.

Is this a triple die obverse? The features are much stronger than a Machine Doubling kind of thing and there is clear separation, IMO.

It is Machine Doubling. This maybe a case where the coin was resonating to produce the tripling, much like a bell resonates when struck. Ken Potter had a coin ( I forgot which denomination ) that showed five distinct doublings. Since these doublings all occur within micro seconds of each other, low resonate frequency against the retreating die maybe the answer for this phenomena.
