Potosi, Bolivia, cob 4 reales, 1650 O, with crowned-F (Mastalir Fb2) countermark on shield and crowned-arms (Mastalir Asb) countermark on cross, very rare, Mastalir Plate. S-P35; KM-17b; Cal-1106. 11.25 grams. A thin and corroded coin (also dark) that somehow only shows important data, including 4-O to left of shield with full countermark in center, clear 50 of date outside of cross with bold but typically partial countermark at edge (double-countermark pieces being very rare in general), one large edge-crack. Pedigreed to the Roberto Mastalir Collection of Countermarked Potosi Cobs, Plate Coin (page 111 in Part A and pages 65 and 357 in Part B) in his book The Great Transition at the Potosi Mint, 1649-1653, The 1649-1652 Crowned Shield Coinage and the Countermarks of 1652 (2021). Recovered from: Capitana, sunk in 1654 off Chanduy, Ecuador
