<p>[QUOTE=&quot;GoldExchangeCalifornia, post: 3583569, member: 104690&quot;]This might come as a shock to you, but <b>the coin was underground</b>. I&#039;ve had countless quarters dug metal detecting that show a corrosive element like yours. The good thing is that it is still worth 0.25!</p><p><br /></p><p>When a coin is underground it is exposed to the harsh elements of nature in the ground, the soil hardens and moistens because of precipitation and the fumes and natural chemicals produced by dead plant remnants in the dirt produce a perfect environment for bacteria and particles that <b>eat away at the clad layers</b> and softer copper compounds. Extreme evaporation in hotter times of the year can also do damage on an object underground with the embedded particles suddenly escaping and creating tiny <b>bubble-like holes in the coin</b>. Although other factors can contribute to corrosion, my example is a more common way a coin can be damaged underground.[/QUOTE]</p><p><br /></p>
