Just picked this up today and it's got my curiosity piqued - it's a 1953 D Franklin Half Dollar (well, that's obvious) that I bought because IMO it is a "Bugs Bunny" Obverse Die Clash (or maybe it's better known as a "Booger Nose" since the clash is under the nostril.) However, taking a closer look at it once I got it home, I'm noticing something really interesting happening under his chin - to me, that looks like a doubled die. There is clearly an extra outline of metal under his chin (nowhere else on the coin that I can see) plus it looks like a slice was taken out of his throat. None of my other dates of BU Franklins have this "slice" - but of the 4 other 1953 D Bugs Bunny Obv Die Clashes I have in my possession, they ALL show it to some degree. (This coin is MUCH stronger than the others, though.) What do you think - is this just a known marker of the FS-402 (looking at the PCGS Price Guide, each of their examples has that slice showing, but none have the extra line of metal under his chin like this example. What's going on here?
