I would normally assume that it&#039;s a measurement error, but it is odd that two scales gave the same result. I hate to recommend damaging a coin, but if the dealer already did a stone test, the coin is already damaged. I might consider nicking it and seeing whether that reveals something else under the gold.</p><p><br /></p><p>I wonder if the dealer&#039;s test could distinguish 24-karat gold (usually used for plating) from 22-karat gold alloyed with copper (the real coin&#039;s composition)?[/QUOTE]</p><p><br /></p>
