This 1 oz. silver medal was struck using a pattern that was intended for a proposed U.S. coin known as the Half-Union. These were to be $50 gold coins that would be issued for circulation, although they were mainly wanted by banks in California who needed an easier way to transfer money. This medal has a proof finish and its production was authorized by the Smithsonian. It was released at the 2017 Denver ANA Show. A mintage limit of 2,500 pieces was set.
The designs on this medal were created by William Barber. Liberty is depicted on the obverse. The intended date of 1877 can be seen here along with 13 stars. An impressive bald eagle design is shown on the reverse. The silver content and face value are inscribed here. If you look to each side of the eagle, you can also see inscriptions indicating its release at the 2017 Denver ANA Show.
