For me it has to be the Indian head penny from the parking lot a gold ring off of the amusement ride and recently a war nickel from a parish panic. I found it because it was on a slope and all the dirt washed away around it
You did good Matt
Found this on the beach while detecting last month. It was wet like it just washed up out of the ocean.
