By 1991, the Silver American Eagle coin program had finally reached the levels of its introductory year in terms of mintage, but did so in interesting fashion.

In 1991, the Gulf War was a concern for the global economy, and that was evident in the spike in production for the Silver American Eagle’s bullion version. After three years of modest increases, the bullion version of the coin went from 5.8 million to 7.19 million in 1991. That wasn’t the only unique factor about the 1991 Silver American Eagle.

From 1988 to 1990, the Silver American Eagle’s bullion and proof coins had each seen modest gains in mintage as demand steadily grew. As such, the overall mintage grew with each year. However, in 1991 the overall mintage grew from 6.5 million in 1990 to 7.7 million, and this despite a big drop in proof production.

The proof Silver American Eagle had a total mintage of 695,000 coins in 1990, but dropped sharply in 1991 to a level of 511,925 coins. This was due in large part to the massive increase in demand for the coin’s bullion version.

On the obverse of all Silver American Eagle coins is the image of Walking Liberty. This full-length figure of Liberty, designed in 1916 by Adolph A. Weinman, features Liberty wearing the American flag around her shoulders and walking toward the setting sun as a symbol of the nation’s drive to discover a brighter tomorrow.

The reverse features the heraldic eagle of the United States, along with engravings of the coin’s weight, metal content, purity, and face value. This image was designed by John Mercanti, Chief Engraver of the United States Mint from 1986 to 2010.
