Republic Real 1846 GC-MP MS63 PCGS, Guadalupe y Calvo mint, KM372.5. Choice Mint State with strong mint luster and attractive surface quality for the designation. A truly remarkable representative of this very scarce issue, currently the finer of only two Mint State certified examples by either major third party grading service, and the finest seen by the cataloguer. The other, a lesser MS62 NGC coin hammered for $4,750 in Stack's Bowers 2011 Baltimore auction (Stack's Bowers & Ponterio 3/2011, lot 8186).
Estimate: 5000-6000 USD
