Black Jack (1927)

Phil Dolan (aka Black Jack because of his talent at cards), Nancy Dolan, and a rustler each have a piece of a silver dollar; each piece has a portion of an indented map of an ore mine. Phil must rescue Nancy from the rustlers to keep their portions of the silver dollar from them. The sheriff's posse captures the gang of rustlers just as they reach the ore mine, ensuring their claim to the mine.
