Do any of you enjoy metal detecting? Any tips on how to best find the "good" stuff from old homeplace??

Question

I now own the homeplace where my dad grew up (he's now a vibrant 80 year old!) We just got a metal detector a few weeks back.. tried it around the old "store" on the property.. have found an old "sinclair pennsylvania motor oil" sign.. with dinosaur logo with "mellowed 100 million years" on it.. it has red on sign... is 24" in diameter.. a round sign... 2 sided... there isn't a "tm" or "r" visible anywhere.... any ideas as to the age (value) of this sign?? ( my dad remembers the sign being there when he was a kid) thanks

Answer 1

Detect around the steps, or where the steps used to be. Also the parking area. As people reach in for car keys, they also pull out coins.
