Your coin is called a Morgan dollar. "American Eagle" coins are modern bullion pieces made since 1986 for collectors and investors; Morgan, Peace, and other standard-issue silver dollars were made for use in ordinary commerce. They were discontinued in 1935. Please see the question "What is the value of an 1880 US silver dollar?" for more information.
