KM-191; Cal-Type-191#681. Moneda Provisional. Armored bust. The single finest graded (by at least 10 points) of the 7 pieces seen at NGC. A high grade example of this crudely produced coinage, with a remarkably clear portrait and a flan free of problems. For the type, about as nice as they come, and a coin sure to attract admirers as it heads to auction.,NGC AU-55.,
