Coin edge
Textured edge of a coin, sometimes lettered
From Wikipedia, the free encyclopedia
Coin edges are the parts of a coin's surface between the faces; they may be plain (smooth) or patterned, or a combination of both. They can also include lettering.
Reeded edges are often referred to as "ridged" or "grooved" (US usage), or "milled" (UK usage).[1] Some coins, such as United States quarters and dimes, have reeded edges. Reeding of edges was introduced to prevent coin clipping and counterfeiting.[2][3]
The main techniques of coin edging are edge mills of various types, which put a pattern on a smooth edge, after a coin and coin mills with edge rings, which pattern the edge at the time when the coin is being milled.
Inscriptions

Examples of edge inscriptions or edge lettering include e pluribus unum on the edge of U.S. Presidential dollar coins, various national €2 edge inscriptions, and various phrases on the UK one pound coin, most commonly decus et tutamen. Inscriptions are more common on thicker, higher-value, or non-circulating coins.
