A clad coin is a type of coin composed of multiple layers of different metals bonded together . This structure can be likened to a sandwich, where an inner core of one metal is surrounded by outer layers of another metal or alloy.
- Multi-layered Construction: Unlike older coins made from a single metal, clad coins are engineered with distinct layers of different metals pressed together under high pressure.
- Core and Outer Layers: Typically, the inner core is a cheaper metal, such as copper, while the outer layers are made of other metals or alloys, often with a silver-like appearance, [according to GovMint] . For instance, many modern US coins, including dimes, quarters, and half dollars, have a pure copper core surrounded by outer layers of nickel.
- Purpose of Cladding: This technique was primarily adopted for durability and cost-effectiveness. By using less expensive metals for the core and more durable or visually appealing metals for the outer layers, governments can reduce the cost of coin production without sacrificing quality.
- Distinction from Bimetallic Coins: It’s important to note that clad coins are different from bimetallic coins. Bimetallic coins also utilize two or more different metals, but they are positioned differently, often with one metal forming an outer ring and another forming a central core, as seen in the Canadian two-dollar coin.
In essence, clad coinage represents a modernization of currency production, balancing economic practicality with the need for durable and secure coins.
What does “clad” mean in a coin?
Good point! Clad Coinage: Coins that have a core and outer layer made of different metals. Since 1965, all circulating U.S. dimes, quarters, half dollars, and dollars have been clad.
What is the difference between silver and clad coins?
Great question! Silver coins tend to make a higher pitched noise, while clad coins have a more dull sound when dropped. Appearance: Clad coins tend to turn more of a copper color as they age, whereas silver coins will become tarnished when exposed to the elements.
