Abstract
A method of making a colored anodized aluminum inner core for making a bi-metallic member, such as a coin or a medal having a metallic outer ring member consists in a first step of anodizing the inner core with a coloring agent so as to create an anodized portion. Once anodized, the inner core is inserted into an inner hollow section of the outer ring member so as to make the bi-metallic member. Once the bi-metallic member is created, it is stamped with an engraving image into a coin, token, or medal.
