Mexico City, Mexico, 1 real, Charles-Joanna, "Early Series," assayer G at bottom between pillars, mintmark M over assayer F/P to left, mintmark M to right, very rare. Nesmith-9 for type; S-M2; CT-135. 3.11 grams. VF with nice inner details but legends truncated (possibly shaved long ago), attractively toned, important as showing a clear M/F/P to left, thus establishing a chronological linkage from P to F to G.
