<p>[QUOTE=&quot;RonSanderson, post: 2697600, member: 77413&quot;]The mint made changes during the previous 20 years to improve the striking. The lettering is thinner, and the alignment of the letters in LIBERTY is more even. The lettering at the rim is taller. The cheek and sleeve have been hollowed out.</p><p><br /></p><p>Here is a comparison 20 years apart. These changes make more metal available for the opposite side of the coin. In theory, this would improve the memorial steps and the lettering in STATES, where the strikes have been weak.</p><p><br /></p><p>[ATTACH=full]606515[/ATTACH]</p><p><br /></p><p>The surfaces are smoother on this 1990-S proof, and the steps are full. I have also attached a more traditional shot where the fields are all black and only the devices are light. While that&#039;s a great look, I like seeing some of the fields at the same time.</p><p><br /></p><p>The detail is really pretty good on these business strikes. The Philadelphia mint needs to address the preparation of the planchets - the surfaces are rough and corrugated.</p><p><br /></p><p><b>1990 Proof</b></p><p><b><b>[ATTACH=full]606514[/ATTACH] </b></b></p><p><b><b><br /></b></b></p><p><b><b>1990 Business strikes</b></b></p><p><b>[ATTACH=full]606516[/ATTACH] [ATTACH=full]606517[/ATTACH] </b>[/QUOTE]</p><p><br /></p>
