I am thinking of starting a new hobby. Going to watch the pawn shop.

The most money we ever found was a jar of coins one time that had been stolen from a bake sale at our local school. Ha, ha.

My grandfather homesteaded NE of the Grand Canyon in the area and his old ranch where my mother lived was one of the places we checked.
The trash dumps again were some of the best.
My mother remembered candy bottles in the shapes of cars, etc. We never found any whole ones and of course the metal detector was no help. Ha, ha.
But it was good to explore and reminisce

We half killed ourselves one time getting to a homestead in SW UT -- down a small cliff and up a canyon. And when we got there we found the remains of a Model-T car(!? ).
It turned out that if you came in from the other direction it was a lot further to go but it was mostly flat -- it could be driven.

Ah, the fun old days.
I wouldn't depend on finding anything valuable with a metal detector. But it's fun and adds to a hike.
