Bicentennial Quarters were minted in 1976 to celebrate the 200th anniversary of the United States. While they may have some value to collectors, it's highly unlikely that one would be worth $1 million USD.
1794 Flowing Hair Silver Dollar: This coin is one of the earliest minted by the United States and is extremely rare. In 2013, one sold for over $10 million USD.
1907 Saint-Gaudens Double Eagle: Designed by famed sculptor Augustus Saint-Gaudens, this gold coin is highly sought after by collectors. One sold for over $7 million USD in 2002.
1804 Draped Bust Dollar: Although technically not minted in 1804 (most were struck in the 1830s), these coins are incredibly rare and highly prized. One sold for over $4 million USD in 1999.
1933 Double Eagle: Only a few were officially released into circulation, making them exceedingly rare. One sold for over $7 million USD at auction in 2002.
1913 Liberty Head Nickel: Only five are known to exist, making them incredibly rare and valuable. One sold for over $4 million USD in 2018.
