Republic gold 10 Dukatu 1951 MS66 PCGS, KM14. Mintage of 100 pieces. One of the classic rarities in the 20th century gold type series. As such, it is rightfully hotly contested whenever one arises for auction. The last record of one selling was actually this past October (Macho & Chlapovic 9, 26 October 2015, lot 293), where an example graded "UNC / About UNC" sold for an amazing 84,000 Euro hammer ($92,685 at the time). An imposing piece in hand, the piece on offer here is a true Gem Mint State piece, with essentially flawless surfaces and superb reflectivity.
Estimate: 50000-75000 USD
