We sometimes see that the edges of the coins have a regular nick. These jagged nicks have a formal name called “edge teeth.”
Why do designers design jagged edges on the edges of coins? Is it for good looks? Is it not easy to slip down in order to get it?
In fact, it is not that simple. I will tell you about it soon.
Why are there jagged edges on the side of the coin? The real reason you absolutely can’t think of
Coin teeth, originally designed by the famous scientist Newton.
In fact, as a famous scientist, Newton died from 1686 to 1727 and has been the director of the Royal Mint.
Why are there jagged edges on the side of the coin? The real reason you absolutely can’t think of
The coinage process at the time was such that the metal was first cut by a cutter that relied on horsepower, and then turned into round silver coins and printed with the help of the craftsman’s eyes and hands. This kind of silver coin is called “making” silver coins.

The most deadly flaw of this silver coin is that it is easy to be emptied.
Think about it too, the surface of the silver coin is only marked with the value of the currency in the middle, and there is no special mark around it, so some people will secretly cut off the silver coin and then let go.
In order to solve this problem, Newton invented the design of the side teeth, that is, the regular marks on the edges of the coins. If someone tries to cut a part of the silver coin, it will inevitably destroy the side teeth of the coin.
In this way, the ordinary people can easily judge whether the coin has been touched by the integrity of the coin.
So everyone may understand that the biggest function of the coin’s teeth is actually anti-counterfeiting.
The casting technology of the side teeth has also been continuously improved. For example, the side teeth of the plum pentagon we cast in the 1990s are intermittent side teeth. The side teeth of the panda silver coins that are issued every year are the oblique teeth, and in the near The side teeth of the Zodiac commemorative coins issued in a few years are the beveled teeth with long and short intervals.
