<p>[QUOTE=&quot;Kentucky, post: 4335542, member: 33176&quot;]It&#039;s hard to imagine a coin completely protected from the environment, even encapsulated examples fresh from the mint will have some environmental exposure because air exchanges somewhat within the capsule, and the metal of the coin interacts with the material of the capsule.&nbsp; When this reaches a point where the coin is deemed to be damaged, we call this &quot;environmental damage&quot;.&nbsp; An improper alloy mix is just that, an improper alloy mix, not considered damage.&nbsp; The woody may have environmental damage, but that is secondary to the damage.&nbsp; Think about it, would a TPG grade a damaged coin...no, they would return it in a body bag.[/QUOTE]</p><p><br /></p>
