This is an interesting and rare dime, part of the Mercury series. It was produced in Philadelphia in 1919 as a business strike. The coin comes with a 10-cent denomination and is composed of .900 fine silver. It is a part of the WWI era, which adds to its historical significance. However, it is ungraded and uncertified. Nonetheless, it is a piece that belongs in any coin collection. Will ship USPS Ground Advantage Service with tracking. Thanks for looking.
