A group of ten stereoviews documenting Pennsylvania anthracite coal mining operations, all published by the Keystone View Company on gray mounts. The views span surface and underground subjects and are numbered within a sequential series, with catalog numbers visible on multiple mounts including 77, 78, 75, 76, and P145. Captions printed on the mounts identify locations including Scranton and Hazleton, Pennsylvania, and subjects range from mine shaft exteriors and coal-laden rail cars to underground tunnel interiors.

Depicted subjects include miners gathered at a cage bottom preparing to descend, electric mine hauling cars loaded with coal on interior tracks, anthracite mine shaft structures with headframes rising above the surface, workers handling coal cars on elevated tipple platforms, and a group scene inside a hard coal mine showing miners with tools under low ceiling supports. One view shows a figure working at a coal face with picks visible in the foreground.

The Keystone View Company, founded in Meadville, Pennsylvania in 1892, became one of the largest producers of educational stereoviews in the United States, and their industrial and labor series documenting Pennsylvania coal country are among the most historically significant records of early twentieth century mining practice.

Caption text on mounts includes "In a Hard Coal Mine, Scranton, Pa." and "Miners Going into the Slope, Hazleton, Pa., U.S.A." among others legible across the two images.
