Watch List notes:

Mexico City, Mexico, 3 reales, Charles-Joanna, "Early Series," assayer R (Gothic) at bottom between pillars, denomination as three vertical bars, no waves, very rare, ex-1554 Fleet. Nesmith-5d type; S-M1; CT-101. 7.55 grams. Broad flan with nearly all details visible despite moderate surface corrosion (VF details), tiny edge-split, darkly toned on fields, minimal doubling. Besides the clear Gothic-R assayer-mark, the most important feature here is the denomination, which is more typically rendered on this brief denomination (wildly popular with type collectors) as three dots, but on this coin it is a lower-case Roman numeral III (with tops connected), which is apparently much rarer. Salvaged from the Spanish 1554 Fleet off Padre Island, Texas, and pedigreed to the Charles Eidel collection. ($5000-7500)
