Rare date/assayer struck at the Mexico City Mint (mint mark Mo), assayer ML.
Rare overassayer variety with ML/F. (obvious and surprising omission by NGC on the label).
Certified by NGC to VF 30.
Well struck except for centers.
Dunnigan Mo16: "This is a very scarce and underrated coin. After the 1833 ML, this date, along with the two 1837s are the scarcest coins of the 1825-1846 period. The overassayer is scarcer than the normal assayer."
