By the end of the 19th century, the 1804 dollar had become the most famous and widely discussed of all American coins. In 1867, one of the original 1804 dollars was sold at auction for $750 ($ today). Seven years later, on November 27, 1874, a specimen sold for $700 ($ today). In the early 20th century, coin dealer B. Max Mehl began marketing the 1804 dollar as the "King of American Coins". The coins continued to gain popularity throughout the 20th century, and the price reached an all-time high in 1999, when an example graded Proof-68 was sold at auction for $4,140,000.
