We believe that the Coatesville Plate Washer Company turned steel plate into washers ( the thin, flat rings with a central hole, used with fasteners like bolts and nuts ) such as the one being sold which was re-purposed as a paperweight. History: Coatesville is, apparently, the only city in Valley Township, a township in Chester County, Pennsylvania. Here is the only reference of note online, with credit to the Valley Township website: “ In 1816, Dr. Charles and Rebecca Pennock Lukens moved to Coatesville and took over the operations of the Brandywine Mills considered the first boilerplate rolling mill in Pennsylvania. In 1890 it evolved into the Lukens Iron and Steel Company named for Rebecca Lukens and was located in Valley Township and Coatesville; Cleveland-Cliffs Inc. now own the Company. During the 1830’s Valley Township had blacksmith shops that were located in the Rock Run section of the township. They were demolished in 1939 due to the expansion of the Coatesville Plate Washer Company. ” There was a sale of vintage Coatesville Plate Washer Company photographs 1922 – 1944 on eBay in 1924.
