Twenty-four vintage American coins certified by Numismatic Guaranty Company® (NGC®) each realized prices over $100,000 in the FUN US Coins Signature Auctioon January 15, 2023.
The top NGC-certified coin was an 1870-S Seated Liberty Dollar graded NGC XF 40 (lot 3766) that realized $420,000. It is generally believed that not more than a dozen 1870-S Dollars were produced, and only nine are confirmed to exist today. These were apparently struck in connection with a ceremony to lay the cornerstone for the new Mint facility in San Francisco.
