Doubled Die Reverse???

OK, I found two Kennedy Halves. A 74 D & 72 D. The 74 D is typical to Mechanical Double, but it is VERY prominent so I am curious, the 72 D however is different, it has distinct raised doubling on "DOL"

Kind of hard to tell with the pictures provided, but I am thinking machine doubling.

Very easy to tell from your photos...MDD.

Kennedy halves of the 70's were notorious for machine doubling.

From the photos, I do not see any MDD. What I see is lack of die filling. The planchet metal didn't get enough pressure to be pushed into the depth of the die ( which translates to the highest part of the details) , such as the "O", so one part ( top of photo)is higher than the other. Same with the vertical of the "D". Not the best of photos to really tell though. This seems to be much more common in larger coins than smaller. IMO. Jim

 

What I see is an area where the reverse die bounced and pushed up the metal, notice the shinny area from the hit. This is so common on Kennedy half dollars. This is why I like to use the term MDD, Machine Damage Doubling.
