Potosi, Bolivia, cob 8 reales, 1652E post-transitional (transitional Type VIII/B), ex-Mastalir collection. S-P37a; KM-21; CT-434. 18.46 grams. Bold full pillars-and-waves despite heavy corrosion (the cross also full but quite weak), darkly toned all over. This coin has a unique feature: The waves below the pillars show an additional four waves at the bottom (nine total), without any obvious double-striking to account for them! Pedigreed to the Roberto Mastalir collection, #VIII.1-B.ba.x(ND)1 in his book (page 223). Recovered from: Capitana, sunk in 1654 off Chanduy, Ecuador ($100-150)
