Antique pocket watch with coin collection in leather case

I lost my antique pocket watch and a small coin collection in a tan leather display case yesterday around 3pm near the Kalispell Library on Main Street. The watch is brass with an ornate back engraving 'E.H. 1863' and still on a short brass chain; the case has a crack along the spine. Inside are a handful of old coins, including a copper Wheat penny and a silver half-dollar. It means a lot to me because it's my grandfather's, and I really need it back.
