<p>[QUOTE=&quot;V. Kurt Bellman, post: 2547753, member: 71723&quot;]When there is a true doubled die coin, that happened (at that time) during the pressing of the hub into the die steel. Frequently more than one &quot;press&quot; would be required to create the working die. All dies were hubbed from plain unmintmarked hubs - ALL of them. Only AFTER the die was made, the mintmark was punched onto them for Denver and San Francisco. THEREFORE, if you DO see a doubled mintmark, it was NOT created during the creation of the die.</p><p><br /></p><p>I believe I read that in recent years, mintmarks are now done to the digital hub itself, before a die is hubbed, but I&#039;m not 100% sure of that.</p><p><br /></p><p>It is theoretically possible for a coin to have BOTH a doubled die AND machine doubling, so it can get weird.[/QUOTE]</p><p><br /></p>
