<p>[QUOTE="calcol, post: 2709678, member: 77639"]You could be right. I don't know enough about metal engraving to know how hard it would be to produce flat fields on a hub. Personally, I could do a better job of that than creating devices, but I'm a better machinist than artist. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" /> The fields wouldn't have to be perfect on the hub. The dies could be polished to achieve that. I think dies were and still are polished after forming with a hub. I've looked in a few references on the early mint and didn't see any pertinent details about hub and die production. Hopefully there is a historical record somewhere.</p><p><br /></p><p>Cal[/QUOTE]</p><p><br /></p>
