Its connection to the nation’s earliest coinage era makes it one of the most important pieces in American history.
The 1787 Brasher Doubloon
Before the U.S. Mint was established, goldsmith Ephraim Brasher produced the Brasher Doubloon, stamping his initials onto the coin. Only a few remain today, and one example reached $9.4 million at auction. It is considered one of the greatest treasures in early American coinage.
The 1822 Half Eagle
The 1822 Half Eagle is one of the scarcest U.S. gold coins, with only three surviving. Two are in museum collections, leaving only one available to private collectors. This extreme rarity pushed its value to around $10 million, making it one of the most prized gold coins ever sold.
The Famous 1804 Silver Dollar
Known as the King of American Coins, the 1804 Silver Dollar was minted in the 1830s for diplomatic purposes, despite bearing an earlier date. Only 15 examples exist. One Class I type sold for $7.7 million because of its legendary status and fascinating backstory.
