Anthracite was found and mined in northeastern Pennsylvania. It is a hard, compact variety of coal that has a submetallic luster, a high carbon content, few impurities, and the highest energy density of all types of coal. Circa 1906, there were over seven hundred mines in operation in the Anthracite Mining Region.
