I have found a 1972 half dollar that seems to have doubling on his profile. It reminds me of the doubling found on the 1966. could anyone be of more help?
Looks like some extreme machine doubling. Even with the coins present wear though it's easy to see that the die that struck it was in rough shape. Which is common for early year clad halfs as the mint was still getting down how to best strike the composition after the switch from silver to silver clad to clad only. http://www.error-ref.com/machine-doubling/
Not a doubled die, imo. It's the old 'mechanical/ejection/strike' doubling, which can be confused with doubled dies..... A fairly common occurrence on many coins, including Kennedy halves.
Though it may be hard to see in this photo, this is a doubled die on the 1966 SMS Kennedy. In hand, you can see the rounded appearance of the doubling which occurs when the working hub strikes the working die slightly "off-target" in a second strike. On your coin, you can definitely see that it is flat and shelf-like. Chris
Thank you for your help everyone. I appreciate your feedback. I'm extremely new to collecting and value the opinions of those more knowledgeable than I.
