Here is a vial of fine placer gold that was panned from the Catawba River in North Carolina. This was the first state in the USA where gold was found, but there are few commercial mining operations in NC today and you don't often see it available on the market. The gold weighs is 1/2 troy ounce, or 15.55 grams
and will ship to you for free with the vial in the picture.
