Vintage coin collection in leather case

I lost my vintage coin collection yesterday around 4pm. It’s inside a small black leather binder with a red velvet lining and a slightly worn spine. Inside are coins from the early 1900s, including a Buffalo nickel with a tiny dent and a 1910 Lincoln cent with a faint maple leaf on the edge. The binder has my initials 'AR' stamped in gold on the cover. I likely dropped it while walking along the Riverwalk near Smothers Park, by Locust Street in Owensboro. This collection is sentimental and irreplaceable; I’d be forever grateful to get it back.
