Cantonal Bank of Zurich, Silver Ingot, 1 Kilogram of Fine Silver 999.0, Nr. 15796

Today, ingots serve in the first place to store value and regulate currencies. Their quantity is under national control in most countries, because it influences the stability of national currencies. To facilitate this control, modern ingots are of standardized weight and fineness. The fineness, is always indicated, together with the label of the producer and the serial number; the latter helps to identify every single ingot.
