Potosi, Bolivia, 8 escudos, 1852FP, large laureate bust facing left, very rare one-year type. KM-115. 27.00 grams. Bold AXF with toning around details but tiny marks in fields and minor rim damage, still a rather acceptable example of this classic rarity with just 6-7 specimens known, the rarest of the Bolivian portrait onzas and interesting for the fact that the denomination was temporarily changed to "8E" for just this type and the less-rare 1851 with smaller bust.
Estimate: $6000
