Sube, I do follow what your saying about nails. The old square nails show as quarters around here and I probably get lazy by days end when I know I’m in an area where squares are, I probably just pass the semi quarter signals. But, dimes signals are different I think. Deeper dime signals should be silver and not iron and my experience is I usually come out with a dime or some type of jewelry. I’m guessing only way to fully get it in my head is to dig a one time signal and see what it is. Guess I’d rather dig nothing than leave something.
