Lima, Peru, 1 sol, 1864/54YB, Arabic 1, "DERTEANO" variety (rare), encapsulated NGC AU 55, finest known in NGC census. KM-196.2. Lustrous (non-toned), with minor marks and hairlines in Liberty-side fields only, crazy variety with the crooked mint director's full name Derteano spelled out on the bottom row of coins spilling from cornucopia and with tiny D's in denticles of rims on that side (at the I in FINO and to right and left of the first A in PERUANA), an illegal and shameless abuse of power by the crooked mint director, who was using the mint as a sort of private bank, this specimen finest at NGC by four grades. NGC #2039763-002. (Estimate: $700 - 1000)
