Coins move through our hands so often that we rarely question their physical features. Yet the ridged edges found on many coins are no accident—they were designed to solve a very real historical problem. In earlier centuries, coins were made from precious metals like gold and silver, meaning their value was tied directly to their weight and purity. This created an opportunity for clipping, a practice where small amounts of metal were shaved off the edges to be sold separately. Over time, widespread clipping eroded the weight and trust in coins, destabilizing economies and undermining confidence in currency.
