Hello, I found a 1992 quarter while roll hunting today and the clad layer is missing. It looks like it has been in circulation for awhile. Any advice would be appreciated.
So the corrosion took the clad layer off? I wasn't sure if that was just light reflecting or what was left of the clad layer. Thanks, I'm still learning and never saw one like this.
The Clad layers on both sides is NOT missing. They are toned. Clad is a combination of Nickel and Copper. It's called Cupronickel. Your Quarter was exposed to long term environmental exposure to the elements, and it toned the copper an ugly color. It is not a mint error of any kind unfortunately.
I'm have been metal detecting for 14+ years. I have found thousands of clad coins and nickels in the same condition as your coin. Environmental exposure means they are buried in dirt, soil and sand for a long period of time. Fertilizer, brackish water, weather and harsh chemicals will tone the Cupronickel clad and nickels. Here are many examples from detected finds. Clad Dimes, Clad Quarters, Clad Kennedy Half Dollars and Nickels can suffer the effects of Environmental exposure.
