Medellin, Colombia, 5 decimos, 1888, classic effigy, NGC AU 55. Restrepo-400.2; KM-165. Fully detailed but somewhat lightly struck, with light rainbow toning over rather strong luster for the assigned grade, a few light marks on obverse, scarce final date of the two-year type with so-called classic effigy of Liberty, unfortunately not so attributed by NGC, whose label just says "PATRIA edge" (presumably the same type), there tied with one other for second finest known behind a single AU 58.
Estimate: 400 - 600 USD
