Absolutely go for it. Hands are in and out of the pocket at every tee box reaching for a tee. Around the greens it's the same thing finding that ball marker. Golfers take off rings, watches and other jewelry before play and stash it somewhere on the cart or in the bag. That stuff falls out all the time. Depending on the age of the course there could be a mound of silver coins waiting for discovery. Focus on the approach to the tee box (the area between cart parking and the tee box itself) and the area between where carts park and the entrance to the green. Also along the cart path where it has bumps, valleys or sharp turns. Good luck!
