MO DPO - Casco - ghost town today - 1899

The post office in Casco, Missouri, served a small, now-extinct community in Franklin County for roughly 37 years during the late 19th and early 20th centuries. The Casco post office was officially established in 1871. It remained in operation until it was discontinued in 1908. Since Casco is now an "extinct" town, mail for this geographic area is typically handled by larger neighboring facilities in Franklin County, such as those in Union or St. Clair.
