Found vintage coin collection in red tin

I found a small red metal tin of coins this afternoon around 3:15pm behind the Fort Dodge Public Library, near the bike racks at the 2nd Ave S entrance. The tin is about 3x2 inches with a dented lid and a faded Fort Dodge Coin Club sticker on top. Inside are roughly 35 coins from the 1940s–1960s, mostly wheat pennies and silver dimes, plus a few foreign coins; they’re in decent condition with natural patina. There’s a handwritten card tucked under the coins that says 'Alex – Fort Dodge'. It looks like a personal collection and I’d really like to see it back with its owner.
