Secrets Stamped in Metal — The Real Purpose Behind Coin Ridges When you hold a coin in your hand, it’s easy to see it as just a medium of exchange or a collectible artifact. But behind its smooth surface lies a hidden layer of engineering and intent: the subtle ridges stamped into the metal known as coin ridges. Far more than decorative flourishes, these ridges hold secrets deeply rooted in history, commerce, and craftsmanship. ### What Are Coin Ridges? Coin ridges, more formally called matting lines, grooves, or ribbing, are slight textured patterns intentionally stamped into the edges of coins during minting. These ridges are not accidental—they serve specific purposes, blending practicality with tradition. Located primarily along the coin’s rim, they enhance functionality while preserving centuries-old minting techniques.
