<p>[QUOTE=&quot;GDJMSP, post: 332119, member: 112&quot;]More a side effect than anything else. They weren&#039;t trying to produce Proof Like coins, they were just trying to do a good job.</p><p>&nbsp;</p><p><br /></p><p><br /></p><p><br /></p><p>Well, they (the authors) are supposed to be the experts, but think about the process of striking a coin combined with the explanation you quoted above. Basining makes the field area of the dies slightly concave. So if the field area is slightly concave then that means that less metal will be pushed up into the devices than if the field area of the dies were left flat now doesn&#039;t it - just common sense. That seems to be contradictory to the explanation the book gives. </p><p><br /></p><p>There was a reason why each mint basined the dies. All the dies were actually made at the Philly mint and then shipped to the branch mints. But Philly didn&#039;t finish the dies, Philly left the final polishing and the placing of the mint marks to the branch mints. So the branch mints that polished the dies, and yet still left them as close to flat as possible were the mints that produced the best struck coins. The branch mints that got slightly carried away with the polishing and left the dies overly concave produced coins that were not as well struck. But yet the polishing did produce coins with Proof Like quality from all the mints. </p><p><br /></p><p>Back then, all the dies were prepared that way. You can find coins of any denomination of Proof Like quality.[/QUOTE]</p><p><br /></p>
