Choice bold strike and satin-smooth fields, encrustation in crevices, slightly crude rims (as made), faint toning and luster, interesting one-year one-denomination issue with mintmark as B to left of assayers' initials T and R (for Truxillo and Rodriguez), apparently their only joint contribution to minting in Colombia, finest at NGC but overall second to a PCGS MS64 that sold for $2000 in 2018.
