Red leather coin binder with world coins

I found this red leather-bound Dansco-style coin binder stuffed with world coins this afternoon around 3pm in the parking lot behind the Flint Public Library on Saginaw Street. It's about 8x11 inches, with a worn spine and gold embossing that reads 'World Coins' on the cover. Inside are roughly 60 coins from the 1800s through the 1960s and a faded inventory card tucked into a sleeve, plus a small velvet pouch. The binder has a couple of unique marks: a tiny dent on the bottom-right corner and a sticky label inside that reads 'Property of PM' in faded ink. This really reads like a genuine collectors item—if you recognize it, I’d love to help get it back to its owner.
