<p>[QUOTE=&quot;Conder101, post: 1251212, member: 66&quot;]I assume you mean on modern coins.&nbsp; The coins from a press drop into a holding bin and every few minutes the pressman picks up a handful and examines them.&nbsp; If there are no problems he dumps the holding bin in with the others.&nbsp; If he does find a problem, such as a die crack, the press is stopped and the die changed.&nbsp; The coins in the holding bin are condemned.&nbsp; Since the coins are checked frequently most die cracks are caught before they have a chance to get very big.&nbsp; Many years ago it was more important for the dies to be used as long as possible because dies were expensive and time consuming to produce.&nbsp; In the late 18th and early 19th century the dies were normally used until they went to pieces.[/QUOTE]</p><p><br /></p>
