Ferdinand I copper Essai 10 Santim 1887-AB MS64 Red and Brown NGC, KM-E3. A beautiful, red-brown rarity with glistening surfaces that promote the coin's well-struck devices. Krause catalog lists this coin with a scant mintage of only 8 pieces, which means that finding another example in this premium quality will be highly unlikely. For reference, we sold a similar example in 2012 that hammered for over $5500.
Estimate: 4000-5000 USD
