"Related to reflectivity is luster. Mint state coins often show a cartwheel effect produced by microscopic flow lines on the coin's surface, such as seen on this 1881-S PCGS MS66 Morgan dollar. As before, the scanner sees the high detail of the coin, but also as before, the coin exhibits a matte surface. Highlights are seen in the hair, however, as the scanner light has reached it at an advantageous angle. In contrast, the camera sees a significant cartwheel on the coin's surface and the coin itself has a more even appearance with the hair no more highlighted than the rest of the coin."
