Silver trumpet with dents, lost near Maryland Theatre

I lost my silver Yamaha trumpet yesterday around 3pm near the Maryland Theatre on North Potomac Street in Hagerstown, Western Maryland. It was in a black soft case with a red strap, and the mouthpiece has my initials 'P.P.' engraved on it. The instrument has two small dents near the bell and a tiny scratch along the bottom valve casing. This trumpet has sentimental value—it was a gift from my grandmother, and I really need it back to keep playing with my band.
