Among the NGC-certified highlights was a 2012 Gold Casascius 1,000 Bitcoin - Unfunded pedigreed to the Otoh Collection and graded NGC PF 69 Ultra Cameo  (lot 30044), which realized $84,000. In 2012, 1,000 Bitcoins would have been worth a few thousand dollars, and had this particular coin been loaded with that value, it would have been worth more than $100 million today, dwarfing the prices for the most expensive coins ever sold at auction. Today, these "Gold Cas" coins are extremely rare, sparking intense interest in the enthusiastic collecting community focused on physical cryptocurrency.
