Gold-tone pendant necklace with initial A

I lost my gold-tone pendant necklace yesterday afternoon in Scottsbluff. It's a slim bar style with an engraved 'A' on the back and a tiny freshwater pearl at the top; the chain is a little tarnished and the clasp is a bit stiff. I was walking from the Panhandle Bank toward Broadway around 3pm, near the corner of 10th Street and Broadway; I think I paused by a small thrift shop and must have set it down. The necklace is categorized as miscellaneous jewellery, but it was a gift from my grandmother and means a lot to me; it’s sentimental and helps me feel connected to her. If anyone found it, please let me know—I’d really appreciate getting it back.
