A coin tree takes the coin string and stands it up: a cast trunk, branches bent by hand, replica coins hung from each tip. It is decorative metalwork, and the good versions are entirely brass rather than plated steel with a bronze wash — the difference shows when the coating wears at the branch joints.
This one is brass throughout on a polished stone base. Branches are rigid; if one bends in transit, ease it back by hand. The coin replicas are modern castings.
