The sterling silver medals are made of silver (99.99% pure), and the sterling silver content of the finished sterling silver commemorative coins is not lower than the international standard of 92.5%. Sterling silver medals have a profound historical commemorative value, which is mainly determined by the commemorative significance of the subject matter, the quality and weight of precious metals, the perfection of artistic design, and the sophistication of engraving techniques and casting techniques. ASNY tells you how to preserve sterling silver medals.
