Republic 1/2 Real 1863/57 C-CE MS66 PCGS, Culiacan mint, KM370.2. Gem Mint State and very attractively toned with a rainbow pattern most satisfying to the eye. In all probability the finest specimen of this rare date. We note a VF example described as "Very Rare date" that sold for $400 over 4 years ago (Stack's Bowers 3/2011, lot 8119).
