This 1955 Franklin Half Dollar is from the Philadelphia Mint in PCGS MS64 condition with the rare Bugs Bunny Error strike. The two "buck teeth" were the result of a obverse / reverse die clash with no coin blank in between. If you line up the reverse at 180 degrees and place is over Franklin the eagles wing tips line up with Franklins teeth. The 1955 Franklin is the rarest but it's even rarer with the Bugs Bunny Error!
