BOLIVIA, Potosí, cob 4 reales, (1651-52) E, with three crown-alone countermarks (rare varieties), two on shield and one on cross (extremely rare with three countermarks), ex-Ponte, Mastalir Plate. S-P36; KM-17b; Cal-Type 279. 12.69 grams. Very broad flan with two edge-cracks from the bold countermarks on shield side, clear but weaker third countermark on mostly flat cross side, lightly toned, thin from corrosion but important as only the second three-countermark 4 reales we have ever offered (for the other, see lot 215 in this auction). Pedigreed to the Luis R. Ponte Collection and plated on pages 284 and 303 of Mastalir's book The Great Transition at the Potosí Mint, 1649-1652: The 1649-1652 Crowned Shield Coinage and the Countermarks of 1652, Part B: The Countermarks of 1652 (2020).
