For example, in October 2019, an 1806 large cent sold for $68,000 at an auction conducted by Heritage Auctions. This coin was graded as Very Fine-25 by Numismatic Guaranty Corporation (NGC), and it is one of only two known examples of the 1806 large cent in this grade.
Another 1806 large cent, graded Good-6 by PCGS, sold for $48,000 at a Stack's Bowers auction in March 2018. This coin is one of only five known examples of the 1806 large cent in this grade.
It's important to note that the prices mentioned above are for coins in relatively high grades. Coins that are in lower grades or have damage or other problems will be worth less.
