<p>[QUOTE="messydesk, post: 3342016, member: 1765"]That depends on how they were prepared. Not all dies are polished to a mirror finish before being put into service. 1921-S Morgans don't exist in PL, but the early die states can have a satiny or frosty luster before the dies start wearing (quickly) through the cartwheel luster to the mushy orange peel luster typical of 21-S Morgans. In all cases, die wear produces flow lines, which give anisotropic reflection as described above. Whether the dies are produced to initially have high specular reflection (mirrored surfaces) or diffuse reflection (frosty cameos, satiny surfaces) doesn't matter. </p><p><br /></p><p>So to answer your question, a fresh satiny die will produce satiny coins until it produces "cartwheely" coins, and a mirrored die will produce mirrored coins until it produces "cartwheely" coins, but a mirrored die won't eventually produce satiny coins, nor will a satiny die eventually produce mirrored coins.[/QUOTE]</p><p><br /></p>
