How do you tell if a coin is missing chrome?

To determine if a coin is missing chrome, inspect its surface for a dull or matte finish instead of the usual shiny appearance associated with chrome-plated coins. Look for areas where the color appears faded or uneven, as this could indicate the absence of the chrome layer. Additionally, you can use a magnet; if the coin sticks, it may not be properly plated. Finally, compare it to a known chrome-plated coin for visual and tactile differences.
