Turkey. Republic silver "Year of the Child" Proof Piefort 500 Lira 1979 PR67 Ultra Cameo NGC, Turkish mint, KM-P1. Mintage: 2,500. Children perform a line dance in the foreground, while a tower-filled city-view resides in the distance on this popular double-thick issue. The mintage is surely overstated in the Standard Catalog of World Coins, as and only four examples have been certified by NGC and PCGS combined. Of the few sales results we've located, most appear to have sold in Europe with prices reaching as high as 1900 Euros (excluding Buyer's Premium).
