<p>[QUOTE=&quot;tomfiggy, post: 2381495, member: 51884&quot;]The MM were punched into the die after the die received the impression from the master hub. That means if the date was doubled on the die itself it&#039;s a doubled die. The MM would not be doubled since it was punched after the hub doubling occurred. Machine doubling happens inside the coining chamber at the time of the striking. The coin bounces or shifts leaving a lighter, flat impression. It is almost always the case that the date and MM would show shelflike doubling since they are so close together. If it is ONLY the MM I would lean toward a RPM. If he would give you a close up pic you could compare it to MM photos on the 3 main doubled die/MM websites most of us check.[/QUOTE]</p><p><br /></p>
