Why were coins minted with serrated edges?

Question

Quizplus · Accepted Answer

Serrated edges were added to coins to prevent them from being clipped or shaved. In the past, coins were made of precious metals like gold and silver, so people would sometimes shave off a tiny bit of the edge and collect the shavings, eventually accumulating enough to resell or use to create new coins. By adding serrated edges, it became much more noticeable if someone had tried to clip or shave a coin, making this practice much less profitable.
