Watch List notes:

Mexico City, Mexico, 4 reales, Charles-Joanna, "Late Series," assayer S to left, mintmark oM to right (S-oM), extremely rare, NGC VF 35, finest and only example in NGC census. Nesmith-78b; Cal-129; S-M8; KM-18. 13.48 grams. Unlisted in Nesmith (tag says "unlisted variety checked by Nesmith" so purchased after his book was published in 1955 but probably before any shipwrecks yielded examples), this rarity boasts nicely contrasting toning with virtually full legends on a broad flan. It's only the third example we have seen, and while each contains the same shield design, the pillars design is different. It's a must-have coin for the serious collector. In addition, a photograph of the shield side of the coin appears in an article Hubbard wrote for a Mexican publication called Artes de Mexico, No. 103, 1968, p. 14. NGC #6448147-009. Pedigreed to the Clyde Hubbard Collection of Mexican Charles-Joanna Coinage (stated on label). Accompanied by original tag or holder from Clyde Hubbard.
