We have 3 Vintage small brass charms,  2 are hearts measuring about 5/8" x 1/2", 1 - 3/8" x 3/8" and the last piece is a decorative oval small "sleeve" (inside is open) which measures about 3/8" x just shy of 3/8" x about 1/8" in D.  I'm not certain what this piece is for.  They all show some light wear.  The larger heart has moderate wear on it.
