Vintage stamp collection binder with rare misprint

I lost my vintage stamp collection binder yesterday around 3pm near the Lexington Public Library on Main Street. It's a red vinyl binder about 11 inches tall, with clear stamp pages filled with US commemoratives from the 1950s to the 1970s. The spine is labeled in black Sharpie 'Midwest Collection' and there's a noticeable crease along the lower right corner. Inside, there are roughly 30-40 stamps, including a rare inverted-cent stamp misprint that I spotted last year; one stamp shows a blue cancellation from 1963. This collection has a lot of sentimental value; it's the culmination of years of work and I really need it back. If found, please message me.
