Charles III Pillar 4 Reales 1770 PTS-JR MS62, Potosi mint, KM49. Brilliant Mint State with strong underlying luster and a few haphazard contact marks preventing a higher designation. An absolutely superb representative of this uncommon and popular type, very rare in this select quality. Currently the only Mint State certified example by either major third party grading service, though a few others also exist (vide the ex-Selschopp/Ortiz 4 Reales 1767 PTS-JR (later sold in Ponterio 1/2004, lot 1524).
Estimate: 3000-3500 USD
