This Pyrite specimen is in the form of a "sun" or "dollar", a flat, round concretion that is found in veins of shale in coal mines. It forms a slightly elongated but nearly complete circle and is in excellent condition, with no visible human-induced damage. Each face of the sun has striations that radiate out from a central point in a 360-degree arc. The dollar has a pale golden color and a bright metallic luster on one side, whereas the other side is much duller. It is a very beautiful specimen, and is thicker than most suns with regard to its diameter. Often this thickness is correlated to a very regular circular shape.
