Republic Proof 50 Pesetas 1957 (1964) PR69 Ultra Cameo NGC, KM-Unl. A intriguing unofficial restrike most likely made fraudulently at the mint. Numismatic sites put the actual number of these Proofs at around 25 pieces and sales are all over the map, ranging from 500 to 5,000 Euros. The present example is among the finer known of this rare, collectible, and somewhat controversial issue that commemorates the 25th anniversary of peace.
Estimate: 1500-2000 USD
