Ethiopia. Provisional Military Socialist silver "Year of the Child" Proof Piefort 20 Birr EE 1972 (1980) PR68 Ultra Cameo NGC, London mint, KM-P1. Mintage: 39. Very rare, this Piefort issue is tied with the Papau New Guinea issue from this "International Year of the Child" set for the lowest reported mintage. Research seems to confirm this piece's rarity, as no individual sales appear in archived auction records. As such, this virtually perfect example should make a wonderful addition to a collection of modern rarities.
