^Lot 531 Mexico City, Mexico, 4 reales, Charles-Joanna, "Late Series," assayer O to left, mintmark M to right

Mexico City, Mexico, 4 reales, Charles-Joanna, "Late Series," assayer O to left, mintmark M to right (O-M), rare. Nesmith-98; Cal-139; S-M10; KM-18. 13.72 grams. An unknown type to Nesmith (although he gave it a catalog number in case one appeared), but at least one other exists (from the Kent Ponterio collection as lot 9169 in the Ponterio auction of August 2009), this broad-flan XF example contains virtually full legends and interiors, with Hubbard notes indicating he originally thought it was attributable to assayer G (due to a flan crack over the O). Pedigreed to the Clyde Hubbard Collection of Mexican Charles-Joanna Coinage (stated on label). Accompanied by original tag or holder.
