Republic silver Specimen Prova 500 Lire 1957-R SP58 NGC, Rome mint, KM-Pr83. Montenegro-01. A popular pattern (of KM98), struck with PROVA along the reverse legend, just to the left of the denomination. This example, despite its light handling, remains rather attractive, with evident reflectivity in open fields and accents of olive-brown tone that concentrate at the edges. Rarely found outside of Europe, this being the first example we've offered.
