<p>[QUOTE=&quot;davedawg, post: 334320, member: 9026&quot;]But wouldn&#039;t the medal have to be displaced somewhere, as in a raised edge or a depression towards the reverse? A dent would not change the weight or mass of the coin, that&#039;s impossible, a dent would have to force the medal to spread to some other point on the coin. For example,&nbsp; a coin put through one of those souvenir machines (i don&#039;t remember what it&#039;s called) that flattens it out does not change the mass of the coin. Only a clipped coin would change in weight.[/QUOTE]</p><p><br /></p>
