Vintage coin and stamp collection binder

I found a vintage coin and stamp collection binder this afternoon around 2:15 pm near the Rosa Parks Museum on Dexter Ave, Montgomery. Inside, there's a green two-ring binder stuffed with coin folders and about 40 stamps from the early 1900s; the coins include a worn 1964 silver half-dollar and a few foreign coins, plus a couple stamp catalog numbers I could spot. The binder's spine has a white sticker that reads 'H. Patel Numismatics 1982,' and the bottom-right corner is dented from a small drop. This collection probably means a lot to someone and I’d love to help return it to its owner if possible.
