Metal, fineness and weight
Each entry states the metal, its fineness or purity, expressed in thousandths, and the weight. From these comes the fine weight, which is the pure metal the piece contains.
The metals in the catalog
Gold, silver and copper are the most common. Platinum and palladium appear mostly in bullion. Bimetallic pieces combine two metals in the same piece, and Others groups rhodium and alloys.
Metal value and collector value
The metal sets the minimum value of a piece at the day's spot price. What is paid above that depends on the mintage, the design, the condition and the demand. The metal value calculator gives you the first part.
