Auction Legends- The Rarest U.S. Coins And Banknotes Of All Time

When rarity, grade, provenance, and collector demand align, a handful of U.S. coins and banknotes turn into headline-making treasures.

A legally ownable 1933 Double Eagle, diplomatic 1804 Silver Dollars, and showstopping paper-money icons like the “Grand Watermelon” note anchor a market where history, condition, and story drive seven- and eight-figure results.

The Crown Jewels Of U.S. Numismatics

• 1933 $20 Double Eagle — The only example legal to own; a once-in-a-lifetime coin that set the all-time record for any U.S. coin. Its unique legal status, storied past, and spectacular preservation make it the hobby’s ultimate trophy.
• 1794 Flowing Hair Silver Dollar — Widely celebrated as the first silver dollar issue; extraordinary strikes and early American history fuel multi-million-dollar prices.
• 1822 $5 Half Eagle — Only three are known today, with two in the Smithsonian. The sole collectible example in private hands is graded AU-50, making it a pinnacle of absolute scarcity.
• 1804 Class I Silver Dollar — Dubbed the “King of American Coins,” struck in the 1830s for diplomatic presentation. Its mythic origin, elite pedigrees, and museum-level rarity keep it near the top of the record books.
• 1913 Liberty Head Nickel — Just five exist. With celebrity provenance and a starring role in pop culture, it routinely commands multi-million prices.

Banknote Heavyweights

• 1890 $1,000 “Grand Watermelon” Treasury Note — Nicknamed for the oversized watermelon-shaped zeros on the back. In elite grade, it set the high-water mark for U.S. paper money.
• “Del Monte” $20 Overprint Error — A famous banana-sticker obstructs part of the overprint, creating one of the most recognizable error notes ever to cross the block.
