Silver harmonica in blue case, key C

Hey, I lost my silver Hohner Marine Band harmonica in a blue zipper case yesterday around 3pm. I last had it after leaving the cafe near the Appleton Public Library on College Ave. The harmonica is key of C, metal with a few light scratches on the back and a tiny dent near the edge. The blue case is a bit worn and has a red star sticker on the front. There's a small fabric tag inside with my initials AY. It has sentimental value—my mom gave it to me when I started playing—and I really need it back.
