Charles-Joanna, "Early Series"
Mexico City, Mexico, 4 reales, Charles-Joanna, "Early Series," assayer R (Latin) at bottom between pillars, motto PLVS in rounded panel, "NIDIA" error, rare.Nesmith-6c/6 for type; Cal-71 type; S-M1; KM-16.13.21 grams.Many details make this an interesting coin. First, it is probably from the "Golden Fleece wreck" (ca. 1550) and hence can be pardoned for having a faint hint of surface corrosion near part of the edge. Second, it contains the very rare spelling error NIDIARVM on the pillars legend. Third, there are identical examples of assayer-P coins (for example, see lot 893 from our Auction 12 of October 2012) making this is a very rare whole-coin die match. Overall it is a well-struck and well-toned AU with lots of desirable traits.
Estimate: 2000-3000 USD
