<p>[QUOTE=&quot;Tamaracian, post: 5437179, member: 23122&quot;]As an example of a coin that was struck with Working Dies that were heavily basined, I post an 1921 High Relief Dollar that I own (my Avatar Image).&nbsp; This coin--especially on the Obverse--exhibits an extreme curvature in the field from the inner Rim to the Portrait; the Reverse also exhibits this curvature, but to a lesser degree.</p><p><br /></p><p>deFrancisci&#039;s design called for ALL Peace dollars to be struck in high relief, but because of poor results and early die failure, the design for 1922-1935 production coinage was modified to be in low relief.</p><p><br /></p><p>From Burdette&#039;s A Guide Book of Peace Dollars (Ch. 3, Pg. 42) &quot;After experience in striking silver dollar, Mint reports relief too great and distribution of areas brings highest relief on each side in center of coin and to attempt to drive the metal into this part of design necessarily brings fin to outer edges and breaks die.&nbsp; Dies can be made to stand only about one hundred tons to square inch.&nbsp; The design is so distributed in circle that in making coin the metal is drawn away from the top and bottom and driven laterally to sides of coin resulting in decided difference in thickness which mars appearance of finished coin and interferes with stacking.&quot;</p><p><br /></p><p>The lighting I used was intended to show the highlights of the varying depth of the field curvature; the coin in hand is much more of a testament to the quoted citation.&nbsp; You will note the more pronounced field curvature at the bottom Obverse, and the Fin at approximately K8.&nbsp; Coins that exhibit the Finning were struck earlier in the coinage run before die failure(s) caused the Mint to reduce the striking pressure; the result being most of the run yielded coins with weak definition on the center of the Portrait.&nbsp; My coin, according to the illustrations and text description on pages 184 &amp; 185 of Burdette&#039;s book, would be classified as a &quot;very well-struck circulation coin&quot;.</p><p>&nbsp;&nbsp; &nbsp; &nbsp;&nbsp; </p><p>[ATTACH=full]1236548[/ATTACH] [ATTACH=full]1236549[/ATTACH][/QUOTE]</p><p><br /></p>
