Potosi, Bolivia, cob 8 reales, (1651-2) E, with uncommon crown-alone (Mastalir K6a) countermark on cross, rare, Mastalir plate. S-P36; KM-19b. 14.97 grams. Bold but corroded full cross with nearly full countermark right on a large edge-crack (perhaps the cause of it), choice full shield without corrosion and with clear 8-E to right, nicely toned in crevices, thin overall but with nice features. Pedigreed to the Roberto Mastalir Collection of Countermarked Potosi Cobs, Plate Coin (page 295 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), with original Herman Moro certificate. Recovered from: Capitana, sunk in 1654 off Chanduy, Ecuador
