The Shape Of Coin

 

WHY IN THE MODERN ECONOMY, COINS ARE SHAPED CIRCULAR?

They were used to square-shaped coins which worked out pretty well then why there was a need for a circular coin.

Well, there are several major and minor reasons for it:-

Major:-

The coins are designed to be durable and semi-permanent. Several coins that are possibly older than you or me are still in circulation. This is mostly due to their round form, which is less prone to wear unevenly. With a round form, no one section of it sticks out more than the others from any angle, therefore no part is likely to wear down. The numerals and impressions may be smoothed down with time, but they would have to be removed altogether.

Coins are flat, thus an image may be readily imprinted on them, because kings wanted their portraits or messages displayed on the coins, coins began to be made in a (usually) round shape. With a 'cast' coin, this is not always straightforward. They would heat a lump of precious metal until it was pliable, then pound the dies with a sled hammer while one person held the ingot between two dies. This typically results in a roundish form. This is still practiced (but instead of hammers, compressing machines are used to print images of great leaders).

Minor:-

The current rationale for round coins is that vending machines and coin sorting equipment require coins to roll. Although coins of different forms may still be made to roll properly, round coins became the industry standard. The same goes for arcade video games and any other machine that requires payment through coins.

A circular, flat form is easy to grip.

The design prevents individuals from injuring their hands when handling them.

Because pressure is properly dispersed in a circular form, the coins are less prone to shatter.
