Vintage coin collection in walnut display case

I’m hoping someone found my vintage coin collection—a small walnut display case with a glass lid and a green felt lining. I last had it yesterday around 3pm, near the Starbucks at the West Village on Lemmon Avenue in Dallas, and I must have left it on a bench outside. The set includes about 20 coins dating from 1902 to 1964, plus one misstrike coin that stands out. The lid has a tiny red enamel star pin attached as a marker, which is my only visible identifying feature. It has sentimental value—my grandfather started the collection, and I really need it back.
