Vintage coin collection in leather-bound case

I lost my vintage coin collection yesterday around 3pm near the Capitol Theatre on Saginaw Street in Flint. It's tucked inside a dark brown leather-bound display case with a cracked glass lid and a brass clasp etched with the initials 'AM'. Inside are about 40 coins set in red felt slots, including a 1909-S Lincoln cent with wear and a rainbow-toned Morgan silver dollar. The case has a small dent along the bottom edge and a faded label on the inside cover that reads 'A. Michaels Collection'. It was my grandfather's, so it has real sentimental value and I’d be grateful to get it back.
