“Ridge patterns on coins are a relic of the past when precious metal coins would be as valuable as their weight. However, some sneaky rogues would shave off the edges of coins and use that metal to mint new coins while spending the shaved coins as if they didn’t weigh less. The ridges were added so it would be obvious when somebody had shaved off parts of a coin and was trying to cheat the system.”
