Republic gold Proof Piefort 50 Francs 1975 PR67 Cameo NGC, Paris mint, KM-P537. A beautifully-illustrative gold piefort, showing full flash within the mirrors and classic cameo contrast upon the devices. Other than the occasional, incidental wisp, the surfaces remain fresh and are replete with golden luster. An impressive denomination in its own right, this double-weight issue absolutely captivates, and with a mintage of just 74 pieces, is scarce in availability as well.
