Keys with red fob lost in Ottumwa

I lost my keys yesterday around 3pm outside the coffee shop on Main Street in Ottumwa. It's a medium-sized metal ring with a red silicone fob and a brass house key engraved 'R.J.' There's also a Toyota car key and a tiny dog-tag that says 'Cora.' The red fob has a small chip and a bite taken out of its edge—the keys look worn but work. They matter a lot to me because they include my apartment key and a sentimental mailbox key from my grandmother; I’d be devastated to lose them. If anyone found them near the Hy-Vee lot behind the Ottumwa Public Library, please reach out.
