Vintage coin collection in red tin

I found a vintage coin collection this afternoon around 3:30pm, lying on the Bricktown Canal walkway near the Chesapeake Energy Arena in downtown Oklahoma City. It’s in a small red metal tin, about 4x3 inches, with a dented lid but everything inside seems intact. There are roughly two dozen coins from the 1920s through the 1960s, including a couple of wheat pennies and a buffalo nickel; one coin has a tiny heart scratched into the edge and a faint 'D' mint mark. The tin lid also has a hand-drawn sticker reading 'C.R. Collection' with a tiny star doodle. If someone recognizes these as theirs, I’d be glad to arrange a meetup to return them.
