Black Ray-Ban Wayfarer glasses with gold hinges

Yesterday around 3pm I left a coffee shop on Grand Ave in Cheyenne, Wyoming, and realized my black Ray-Ban Wayfarer glasses were missing. They are mid-size with glossy black acetate frames and a tiny gold hinge on the left temple. The right lens has a small scratch near the bottom, and there’s a discreet engraving 'RP' on the left temple. They were a gift from my grandfather, so they mean a lot to me and I would really appreciate getting them back.
