Gold-tone hoops with star and moon charms

I found a pair of gold-tone hoop earrings this afternoon around 3:20pm near the Brownsville Museum on 6th Street, along the riverfront boardwalk. They're small hoops, about 1.4 cm in diameter, with light wear and no stones missing. One earring features a tiny enamel blue star charm on the outside; the other has a tiny crescent moon charm on the inside back. There's a faint engraving on the inner clasp that looks like 'A1'—not sure if that's a brand, but it might help identify them. They seem possibly sentimental, and I'd love to get them back to whoever lost them.
