Black Coach briefcase with coffee stain

I lost my black Coach leather briefcase yesterday around 3pm outside the Virginia Museum of Fine Arts on Arthur Ashe Boulevard in Richmond. It's about 15 inches long with brass hardware and a sturdy, slightly frayed handle. The outside has a small coffee stain on the top corner and a shallow scratch along the bottom edge from daily commuting. Inside there's burgundy lining, a red leather tag embossed with my initials RP, and a few client proposals in a manila folder. It has sentimental value and I really need it back—it's my main work briefcase and it carries my current projects.
