<p>[QUOTE=&quot;lawdogct, post: 110676, member: 1476&quot;]If the coin was subject to abrasion, why would the zinc lines be raised up?&nbsp; I don&#039;t want to come across as argumentative here, I&#039;m quite happy to agree that it was altered outside the mint, I just can&#039;t wrap my mind around how abraision could raise the metal in lines instead of cutting &quot;valleys&quot; into it.</p><p><br /></p><p>Only thing I can think of is that the abrasion resulted in the copper layer being &quot;cut&quot; through in lines.&nbsp; Next. the exposed zinc corroded causing it to become elevated.&nbsp; And finally, subsequent wear polishing the exposed corroded zinc lines back into a silver color.</p><p><br /></p><p>I know its darn near impossible to account for what happens to coins once they leave the mint, but this one has definitely grabbed ahold of my curiousity.[/QUOTE]</p><p><br /></p>
