Vintage stamp & coin collection in red tin

I found a vintage stamp and coin collection this afternoon around 3:45pm beside Bronson Park, downtown Kalamazoo, near the Kalamazoo Institute of Arts. It's kept in a small red metal tin with a clear lid; inside there's a mix of stamps from the 1940s and coins, including a shiny 1947 Wheat Cent and a handful of foreign denominations. There's a faded label on the tin that reads 'G.H. Collection' and a tiny maple leaf doodle drawn in pencil on the lid. It feels like a personal keepsake, something someone clearly put time into, and I’d be happy to help get it back to its owner if this looks familiar.
