Republic Proof 50 Centesimos 1916-(ba) PR61 Cameo NGC, Buenos Aires mint, KM22. The scarcer date of this two-year type, and apparently unrecorded in proof, the piece at hand appears to be only example in the designation that has appeared at auction. Thus, exceedingly rare. Though lightly handling, the fields appear fully glassy and mirror-like with sunny yellow light throughout and pinpoint-level detail.
