1966 Kennedy question P mint.

6 posts in this topic

Found this 1966 P Kennedy with doubling on the right wing tip feathers and in the lettering to the right. Can it be a double die?

Hello Errorist,

Well, in looking at your photos, I'm not seeing any doubling that is readily apparent.  Therefore, I'm going to guess that your coin either has some machine doubling or it could be a doubled die, but a fairly minor one.  However, since I couldn't see the doubling in the photos, I cannot be exactly sure which.  I favor the machine doubling hypothesis, though, as the type of doubling is pretty common on US coins of this age.

I hope this was of some help!

I think I see what you are referring to now......that really didn't jump out at me at first.  I'm going to say that is definitely machine doubling.  It's quite subtle and if you look at it, it's shelf-like in appearance.  That's a hallmark of machine doubling.

Wouldn't machine doubling occur on the feathers below those three? Why only on the three feathers??

Machine doubling doesn't work like that.  Here's an article that explains it:


it can be very localized, in fact it's often more localized than true doubled dies are.  Many of the most famous doubled dies impact multiple devices on a coin.  Check out the 1955, 1969-S and 1972 Doubled Die Lincoln Cents and you'll see what I mean.  The fact that it only affects those three feathers, to me, is actually a further indicator of machine doubling.
