This is a really nice token. The ship is docked in the Baltimore Harbor today. In recent times it has been sailed to other cities for display for certain events. These tokens state that they were made from parts of the ship, from the Frigate Constellation, which was the first ship of the U.S. Navy.
USS Constellation is a sloop-of-war, the last sail-only warship designed and built by the United States Navy. She was built at the Gosport Shipyard between 1853 and 1855. She was named for the earlier frigate of the same name that had been broken up in 1853. So you are aware, there is a USS Constellation docked in Baltimore Maryland. It is the Sloop of War Constellation (1854) and not the Frigate Constellation (1797). For a while there was a belief that they were one in the same through an extensive rebuild. But later on through intensive research it was determined that the original was broken up in 1853 and the one currently in Maryland is the Sloop of War USS Constellation (1854) was built close by as her substitute.
These are neat. I've seen a few and might have had one once. Don't remember. I know I had a USS Olympia medal struck in bronze from the ship's propeller. But that ship was from almost a century later (Spanish-American War).
