Watch List notes:

Mexico City, Mexico, 1 real, Charles-Joanna, "Late Series," assayer S to right, mintmark M to left (M-S), very rare, NGC AU 58, finest known in NGC census. Nesmith-76; Cal-67; S-M8; KM-9. 3.38 grams. This is the only Nesmith variety known to exist in this denomination (probably meaning very few were minted), and while not extremely rare, it is hard to find in this condition, with frosty surfaces and low contrast toning, full legends and interiors. NGC #6448147-007. Pedigreed to the Clyde Hubbard Collection of Mexican Charles-Joanna Coinage (stated on label). Accompanied by original tag or holder from Clyde Hubbard.
