A one-pound bar of .999 fine copper cast in a trapezoid shape, sold as a desk paperweight and marked with the element design. It is a solid piece of metal, not a coated weight, and it comes with a certificate of authenticity from Unique Metals. The draw is the material and the look: real copper with a heft that holds papers down and a shape that reads as a science or lab object. Against plastic or brass-toned paperweights it offers more weight and a purer metal, but it tarnishes over time and is not a collectible coin. It suits chemistry teachers, students and desk-accessory buyers more than investors, since copper bullion carries little premium and is hard to resell at a gain.
