Known as "The King of U.S. Coins," the 1804 dollar is extremely rare, with only 15 known examples. Class I 1804-dated silver dollars were actually struck in the 1830s when the United States Mint was asked by to produce them for sets of U.S. coins to be presented to foreign dignitaries. Class III specimens (six known) were struck during the 1850s for collectors. The Idler/Bebee specimen was donated to the ANA by Aubrey and Adeline Bebee.
