Red leather coin album with mixed era coins

I found a red leather coin album this afternoon around 3:15pm behind the Chauncey Swan Parking Ramp in downtown Iowa City. The pages are filled with coins from the 1800s to mid-1900s, some with a warm patina. One page has a tiny pencil note saying 'Nov 1927' and a stamp-like coin with a faint mint mark; the album cover has a small scuff but the whole thing seems well-kept. It looks like someone spent a lot of time curating it, and I can tell it has sentimental value. If you’re missing this or know who it belongs to, I’d like to help return it.
