<p>[QUOTE=&quot;SuperDave, post: 2290042, member: 1892&quot;]It&#039;s not uncommon for a piece to break off of a die during use. There are some titanic forces involved - striking pressure is some 150 tons, and they run at least 150 strikes per minute. And when you contemplate the design complexity of a given die, it makes sense that there will be areas on the die where pressure is greater than others during the strike. It&#039;s why you see the insides of mint marks and letters break off so often.</p><p><br /></p><p>So, yeah, I&#039;m thinking this is one of those small failures, called a die chip. Larger versions are called &quot;die breaks,&quot; although there&#039;s some argument in numismatics (no, we can&#039;t agree on what the words mean <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" /> ) that a &quot;die break&quot; ought to be a development of a die crack.[/QUOTE]</p><p><br /></p>
