Potosi, Bolivia, cob 4 reales, Philip II, assayer R (Rincon) to left, rare, PCGS XF details / tooled, ex-Ugaz. S-P1; KM-4.2; Cal-518. 13.26 grams. Superb broad-flan piece with choice full details on both sides including the crown and both legends (just a trace of doubling on reverse), with deep rich toning all over, the stated tooling no more high-point abrasion on crown, truly a lovely example of the desirable first issue of the Potosi mint. Pedigreed to the Jorge Ugaz collection.
