It varied by series and era, of course, but yes, for many series there is a single mintmark punch that was used for many years. You have unique and identifiable mintmarks because of this. For example, on the Mercury dime series, there were three different D punches used for the entire series (and the same punch was also used on Lincoln cents of the same years), or 7 different S mintmark punches used for the entire series. </p><p><br /></p><p>David Lange, in his &quot;Complete Guide to Mercury Dimes&quot; discussed these and shows pictures on pages 34-35.[/QUOTE]</p><p><br /></p>
