We hand cut a 4 piece necklace set from a real half dollar so each piece holds the shape of each different dinosaur (alternating) and then connects them together to form the whole coin again. If your child loves dinosaurs then this coin set is made just them and their closest friends! A skilled craftsman works on each coin to ensure quality, first starting with holes from a drill press and then hand cutting each line with a Jeweler's Saw. Cutting into large coins like beautiful Real Silver Half Dollars & Dollars takes a lot of work. Because of the greater thickness and surface area of these coins it makes them a much harder project than just cutting from a quarter, but it is always worth the effort!
