Republic brass Gold-Issue Uniface Trial 1500 Pesos (1968-9) PR65 Ultra Cameo NGC, KM242 (obverse trial). Starkly cameoed on the bust of Bolivar with reflective fields. The unstruck side is stamped "MET." inside a square with "GORI & ZUCCHI" below. A short search reveals Gori & Zucchi as an Italian firm that was founded in 1926, reached its peak in the 1960s around the time these trials were produced and today employs about 500 people.
