Known officially as the 1899 One Dollar Silver Certificate, the Black Eagle was the popular name for this one-dollar certificate from the United States Mint. The original certificates were printed by the Mint from 1899 to the early 1920s, with its replacement by a new note design completed in 1923. The Black Eagle was the second most common large-size note from the US Mint, and featured the Eagle of the Capitol design offering shelter to portrayals of Presidents Abraham Lincoln and Ulysses S. Grant. Roughly 3.2 billion notes were printed while the Black Eagle was in circulation. On the reverse youll find the design used on the original $1 bill certificates issued by the United States Mint. The design is a simple one that features the certificates value as both One and 1. Above the central design is the engraving Silver Certificate, while United States of America is featured below. Each of these 1 oz copper bars is engraved in the United States at a private minting facility, and capitalizes on the increasing value of copper in an extremely unique fashion.
