Brass keys on red lanyard lost near library

I lost my brass house keys yesterday around 3pm near the Potsdam Public Library on Park Street, in Potsdam-Canton-Massena. They’re on a red woven lanyard, a bit frayed at the ends. The set includes four keys: a Schlage front-door key, a Yale deadbolt, a small brass skeleton key, and a USB key with a peeling white label. One key has a blue plastic head that’s cracked, and there’s a tiny brass tag engraved 'Milo' hanging from the lanyard. The brass is a bit dull and the whole thing shows some wear. This set is essential to me and has sentimental value; I really need to get it back. If anyone found them, please reach out to me.
