Silver Yamaha trumpet with orange-lined case

I lost my silver Yamaha Bb trumpet yesterday around 3pm near City Hall on Broad Street, right by the fountain. It's in a black hard case with an orange interior, and the trumpet itself has a couple of tiny dings on the bell. There’s a small sticker with the initials 'AR' on the lid of the case, and the mouthpiece has a faint scratch. This instrument means a lot to me because it was a gift from my aunt, and I really need it back to finish up auditions.
