But it is the die flow lines created in the die face that produce the mint luster (according to the link).

When a coin is struck, the metal flows up into the recesses in the die, filling out the details and causing raised areas, which we see as devices, letters, etc. As it flows, the metal wears on the die; because the metal flows the same way each time, it will wear &quot;grooves&quot; into the die. I say &quot;grooves&quot; because I can&#039;t think of a better way to describe it - in numismatic parlance we call them flow lines. These microscopic lines reflect light in every direction, causing the diffuse shine that we call luster. Because luster is caused by wear on the die, later die states often have better luster. A brand new die will occassionally even be prooflike - having a mirrored surface and no cartwheeling luster. These prooflike coins are highly prized by collectors. As the die wears, the flowlines become etched into the die. The striking of coins wears the die down, often softening the details, until finally you get a late die state coin. <span style="color: #ff8000">By this point, the flowlines are strongly etched into the die, and you will sometimes get incredibly flashy luster.</span>&quot;[/QUOTE]</p><p><br /></p>
