Watch List notes:

Potosi, Bolivia, cob 8 reales, Philip II, assayer C under erasure, very rare, Grade 1, ex-Research Collection (Plate Coin). S-P5; KM-5.1; CT-136 (under La Plata). 25.40 grams. With bold P-erasure-C (the erasure believed to be B/L with the B contrived from an S-punch) to left of a full and well-detailed shield, the cross-lions-castles also full and bold, light surface corrosion only in part of periphery, this is a very nice example of a classic rarity that was re-attributed to Potosi after new research presented in 1988 (after the bulk of Atocha coins were certified), one of very few known from the Atocha and further desirable for its RC pedigree. Pedigreed to the Charles Eidel collection, with special Fisher photo-certificate #237189 (described as La Plata mint) and Plate Coin #4 in the Atocha Research Collection (Christie's, 1988). Recovered from: Atocha, sunk in 1622 west of Key West, Florida ($2500-3750)
