According to error coin collector enthusiasts and numismatists, a ten plus percent misaligned die is a great error on any denomination, and almost unheard of on a bicentennial half dollar.

However, it does happen and even a minor example error coin is still a rare collectible.

Misaligned die errors occur when the anvil usually the reverse die stays in its proper orientation but the upper hammer die becomes misaligned.

The result is that the obverse appears to be off center and it is not until you flip the coin over and see that the reverse is still centered that it was struck by a misaligned die”. – numismaticsnews.net

How to Identify the Bugs Bunny Half Dollar

A  die clash occurs when the reverse die, featuring the Liberty Bell and eagle, strikes the obverse die, featuring Franklin’s portrait, with excessive force.

Furthermore, a 10x loupe is enough to view it, but I used a mobile phone and a Carson zOrb USB digital coin microscope to capture these photos.

The impact results in a raised portion on Franklin’s upper lip, resembling the famous Bugs Bunny cartoon character’s buck teeth. 

Note the arrows noting the eagle’s wing imprint creating a buck tooth appearance on Franklin’s top lip.
