It's a pleasure.
Odd but I do recall that the ancient Athenian Greeks circulated Iron as money with a reason we may not find obvious.
Well I do have a small 1/10 Troy oz. coin and a tiny Platinum bar as a gift from a wonderful friend but never considered these as alternative since they have had no history as a monetary metal. I agree that Platinum as a precious metal yet no history as a monetary one.
