<p>[QUOTE=&quot;physics-fan3.14, post: 2354756, member: 19165&quot;]To return the thread to the original question, &quot;Do Prooflike Coins have Cartwheel luster?&quot;, the answer is a resounding &quot;yes.&quot; The character, however, is going to be completely different. Let me present Exhibit A, a PCGS 65+ DMPL Morgan. The luster is more evident in my reverse pictures, but it is present on the obverse. Look in the fields, how there are bands of luster. This appears &quot;under&quot; the mirrored surface, but it gives the appearance of a cartwheel (in hand, it moves just like a regular cartwheel). These are solely from the movement of the metal - a DMPL is going to come from a freshly basined die, where there has not been any wear on the surface of the die. This only happens to dies which have been basined (polished) - not all dies are polished before being put into service. A normal die will have a diffuse surface.</p><p><br /></p><p><img src="http://i277.photobucket.com/albums/kk68/physicsfan/prooflike/IMG_0575%20copy_zpsnhbpgzkp.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><img src="http://i277.photobucket.com/albums/kk68/physicsfan/prooflike/IMG_0580%20copy_zpsmdabt9so.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><br /></p><p>Exhibit B, a PL Barber Quarter. Notice, especially at the rims of the obverse and the top of the reverse, the flow lines from the movement of metal. This is what creates luster:</p><p><br /></p><p><img src="http://i277.photobucket.com/albums/kk68/physicsfan/prooflike/IMG_9814copy_zps5a227ce6.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><img src="http://i277.photobucket.com/albums/kk68/physicsfan/prooflike/IMG_9828copy_zpsc86b6af1.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><br /></p><p>I don&#039;t collect Proof coinage, so I don&#039;t really have any pictures to post of proof coins. However, the effect is nearly exactly the same.[/QUOTE]</p><p><br /></p>
