HUNGARY. Ducat, 1679-KB. Kremnitz Mint. Leopold I (1658-1705). NGC MS-66.Fr-128; KM-151. Boasting stellar vibrancy and execution with all the details within the standing king and Madonna motifs being fully rendered. Despite being from a long issued type (1659-1704), few have survived looking like this. Truly a Gem, worthy of the finest collection.NGC MS-66.
