Silverbacks is the term for a specific collection of Silver Notes. The introduction of Silverbacks came as a direct alternative to the rising popularity of modern Goldback Gold Notes. The advantage of Silverbacks lies in both the beauty of the designs, but also, the affordability of silver. While the need for hyper-fractionalized silver is not evident at the moment, the beauty of the design for Silverbacks nonetheless stands out as a main attraction for these pieces.
