Several things apply here. One, does it have a name on it? example: I was driving down the road with my 5 kids and we spotted several hundred dollars in cash floating around in the road. We got out and grabbed it. We were totaling it up when my son said " I even found the wallet". I said let me see it. It had full ID including the guys kids pictures. I collected the money and wallet and we drove over and returned it. This is a true example.
Example 2: This is fiction! Detecting in the desert and get a loud signal. Uncover very old gold cross and other gold items with jewels. What woud I do? Actually there's no question there. I would carefully pick out the jewels and melt the gold down to small 1 oz. bars. I would then take an extended trip around the USA stopping in many jewerly stores and selling it off one piece at a time and vastly enjoying the trip. LOL
Religion does not enter into this equasion!
