How long does it take for a coin to break down?

Answer 1

Coins are typically made from durable metals like copper, nickel, and zinc, which can take many years to break down in natural environments. While they can last for decades or even centuries without significant degradation, factors like corrosion, exposure to elements, and environmental conditions can affect their longevity. In landfills, coins may remain intact for thousands of years. However, in specific conditions like seawater, they may corrode more quickly.
