The Ridges Around the Edges of Coins
The next time you hold some coins in your hands, feel them around the edges. You should notice that some coins, like dimes and quarters, have ridges on the edges. Ever wondered why? It’s not just for decoration! In fact, this all goes back to the early days of coins, when each one was made with a different metal, and the weight of each coin was directly proportionate to its value.

To try and get more bang for their buck, some people would shave off little bits of the metal and then use it to make more money. So, the ridges were added to prevent this from happening further.
