Sterling charms are tested sterling.  Chain tests sterling, also.  Charms include:  tea or noodle cart, bird cage, ship, abacus with moving beads, water pipe, rickshaw, articulated fish, and a pagoda.  The chain does not have a ring on the end for the clasp to catch.  The chain is 5 ½" long and is most likely missing some length as well as the o-ring on the end.

See photos, a dime is used for scale in the last photo.
