Potosi, Bolivia, cob 4 reales, 1652 E, with uncommon crown-alone (Mastalir K4r) countermark on shield, extremely rare (one known), ex-Ponterio. S-P36; KM-17b; Cal-unl (Type 279). 7.76 grams. A Royal-like coin (round, well centered and fully detailed) that is unfortunately thin from corrosion but has the distinction of being the ONLY shield type 4R 1652 known to exist so far, with all details clear (just the bottom of the 52 of date) and the countermark on the shield full and bold, with lovely toning all over, a unique opportunity for the dedicated 4R collector. Pedigreed to the Roberto Mastalir Collection of Countermarked Potosi Cobs, Plate Coin (page 158 in Part A and page 267 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), and also pedigreed to the "La Capitana" auction by Ponterio (April 1999), with original lot-tag 22 and generic certificate. Recovered from: Capitana, sunk in 1654 off Chanduy, Ecuador
