Brass compass with initials engraved

Lost my small brass compass yesterday around 3pm near the Pearl Street Mall entrance by the Boulder Creek path under the 9th Street pedestrian bridge. It's the size of a car key, with a warm patina and a tiny dent on the rim. On the back, someone engraved the initials 'A.J.' and a red thread is tied to the ring. It means a lot to me for upcoming weekend hikes; it's a reminder of my dad who gave it to me. If anyone picked it up, please drop it off somewhere safe or message me; I really need it back.
