Found vintage coin collection with display case

I found a small vintage coin collection this afternoon around 2:15pm in the parking lot behind the Copper Harbor Lighthouse gift shop on M-26, in Michigan's Upper Peninsula. It's housed in a red velvet-lined display case with a brass latch and includes coins from the early 1900s, plus a tiny photo of a woman in period dress tucked between the pages. I wasn’t sure who it belonged to—locals or a traveler—but it looked valuable to a serious collector. If you’re missing it, tell me the exact coins you saw and anything written on the display case so I can get it back to you.
