<p>[QUOTE=&quot;maridvnvm, post: 3409433, member: 31620&quot;]Why do you say that?</p><p><br /></p><p>There is a working theory that has developed out of a&nbsp; combination of such errors turning up and through experimental archaeology that a single obverse die was used with two, alternating reverse dies. If a single reverse die is used repeatedly then the reverse die tends to overheat quite rapidly and is very prone to breaking. If you alternate reverse dies, perhaps on a rotating yoke of some form then the dies have a chance to cool a little between strikes. This has been demonstrated to greatly extend the life of the reverse dies.</p><p><br /></p><p>Several coins have turned up that exhibit this type of effect, the one above being one of two that I have owned.[/QUOTE]</p><p><br /></p>
