Red enamel mug with chip and star stamp

I lost my red enamel mug with a white interior yesterday around 3pm near the Starbucks on Market Street in the Gaslamp Quarter, San Diego. It’s a sturdy mug, about 3.5 inches tall, with a tiny chip on the rim and a small star stamp on the bottom. It’s from a local shop and has sentimental value—a gift from my grandmother that I used every day for coffee. I really need to get it back; it’s become part of my morning routine. If anyone found it, I’d be grateful to reunite it with me.
