<p>[QUOTE=&quot;Hobo, post: 1202490, member: 11521&quot;]Are you saying the copper-nickel clad layers dissolve over time when a coin is buried in the ground? </p><p><br /></p><p>I have dug numerous clad coins and they were generally tarnished (like the coin in the OP). I have never seen nor have I ever heard of copper-nickel dissolving due to being buried in the ground. </p><p><br /></p><p>If copper-nickel (75% copper / 25% nickel) will dissolve due to being buried in the ground we would not be able to find buried nickels (which are the exact same composition as the outside clad layers of clad coins). Metaldetorists regularly find Shield Nickels (1866-1883), Liberty Nickels, Buffalo Nickels, and Jefferson Nickels buried in the ground and they have not dissolved, even after 145 years in the ground.[/QUOTE]</p><p><br /></p>
