Charles-Joanna, "Early Series"
Mexico City, Mexico, 4 reales, Charles-Joanna, "Early Series," assayer G at bottom between pillars, mintmark M to left and mintmark M over assayer F to right (oMo-oM/Fo), very rare, ex-Jones (Plate Coin).Nesmith-unlisted; Cal-69 type; S-M2; KM-unl.13.20 grams.A Nesmith #11 type with the right M mintmark punched over an F from the previous assayer, but unlisted in his catalog since he had never seen a coin with an overassayer. Had he done so, he probably would have put the assayers in the correct order we know today. This scarce type is a choice AU with very light toning, full legends and very minor corrosion at edge (probably from the "Golden Fleece wreck" of ca. 1550).Pedigreed to the Dr. Peter Jones collection, plated on page 73 of his book The First Coins of the Americas (2020), and to the Ponterio auction of November 2002, with original lot-tag #1009.
Estimate: 1750-2500 USD
