<p>[QUOTE="GDJMSP, post: 1868306, member: 112"]That is correct. The irregularity of the wear lines in the die increase the refraction and thus decrease the reflection. But the exact same thing happens with business strikes too. And that's why coins struck with new, fresh dies have a better quality luster than coins struck with worn dies.</p><p><br /></p><p>But a lot of people don't understand that.

The more refraction you have, the less reflection you have. And what reflects light the best ? A mirror. And what looks like a mirror ? A Proof coin.
