Black Ray-Ban glasses with blue temples

I lost my black Ray-Ban Wayfarer-style glasses yesterday around 3pm near the Missouri Theatre on 9th Street in Columbia. They're matte black with blue temple tips and clear prescription lenses; the left lens has a tiny scratch I didn't notice until later. The frames are a bit worn but still sturdy, and there's a small engraving on the inside of the right temple: 'AB'. They came with a brown leather case that has a faint coffee stain. These glasses mean a lot to me, they were a gift from my grandmother, and I really need to find them.
