Brasher Doubloon – up to $9 million
Wikipedia
The Brasher Doubloon is an iconic and rare American gold coin, created by silversmith and goldsmith Ephraim Brasher in 1787. This historical coin, considered one of the first gold coins struck in the United States, features a distinctive design with a heraldic eagle on the obverse and a sun over mountains on the reverse.
Brasher, who was also a neighbor of George Washington, stamped his unique hallmark on the eagle’s breast, consisting of his initials “EB” and a small punch that resembled a cornstalk. Only a small number of Brasher Doubloons are known to exist, making them highly coveted by collectors.
