Black keyring with red tag and compass

I lost my keys yesterday around 3pm near the Super One Foods on Tower Ave in Superior, WI, in Northern WI, by the canal behind the grocery lot. They’re on a black metal keyring with a red plastic tag marked 'M4' and a tiny brass compass pendant that can slide along the ring. There are a few house keys, a Ford car key, and a faded gym sticker on the back. It’s particularly sentimental because one key is my grandmother’s old house key, and I really need it back. If anyone finds them, please drop them at the Lost & Found desk at city hall or message me through this app.
