Potosi, Bolivia, cob 8 reales, 1649 O/Z, with crowned-O countermark on cross, ex-Mastalir (Plate). S-P35; KM-19b; Cal-1486. 23.76 grams. Atypically non-salvage yet still underweight (as made, the problems at the mint not fully eradicated at this point), with very bold P-O (the under-letter Z barely discernible), choice full countermark near center of full cross with full 164 and faint trace of 9 of date, deeply toned AVF with large edge-crack. Pedigreed to the Robert Mastalir Collection and plated on page 51 of Part A and page 177 of Part B of his books The Great Transition at the Potosi Mint, 1649-1652: The 1649-1652 Crowned Shield Coinage and the Countermarks of 1652 (2021).
