Or found outdoors and starting to show a residue on the coins surface. Note the areas where this residue has worn off the coin. This will show the normal color as it rubs off the coin. If this were a missing cladding, then it would be red in color like the copper edge seen on the normal quarters:


Partial clad missing. Note the red color, like copper cents. Note the struck area is strong. Not ghost like. These are collectable.

On the top coin, the cladding was removed post strike. If left alone it would have been worth more as a clam shell clad issue. The missing area will show a ghost image strike on the area that the clad was removed.

But if the color is brown rather than red, then it is probably a metal detector find.

The longer left out in the wild, the stronger the residue will be on a coin. (Homelessness sucks even for coins)
CoopHome: Does a brown color on a coin mean a good thing for the coin? no. if it is residue from being left outdoors, then it is not a plus. This wear off the coin later on. On a missing clad, the strike can be weaker because of the missing height on the planchet. So look for a red color, not a brown color for the missing clad coins.
