August - 'The most attractive non-circular coin'

30/8/2023

0 Comments

 
Our regular group of six coin collectors were presented with a real challenge with the August Coin of the Month being the most attractive non-circular coin.

Most coins are circular because of ease of production and their shape does not wear holes in clothes pockets. The most common non-circular coin we are familiar with is the Australian 50 cent piece which has 12 sides and called a dodecagon. We were presented by one of our members with a beautiful collection of silver and gold 50 cent coins (see photo below), most of which none of us have ever seem; what a treat!

We were also presented with a number of other non-circular coins including a 7-sided 50 cent piece (heptagon), a 12-sided three pence from the UK and a Hong Kong 12 point scalloped 20 cent piece.

Most of our modern circulating coins are round because a round shape is less likely to wear down unevenly since no one part of it sticks out further than the rest from any angle.

Also, in the days when coin value was assessed by metal type and weight, it was easy to cut off the corners but more difficult to do that with round coins. Milling of the coin edges also limited this practice especially when coins were made of precious metals like gold and silver. Then in the modern world there were vending machines which need coins to roll.

Coin of the Month for September will be “let’s talk about the Australian penny and its dots”.

    Coin Collectors

    Coin Collectors is a group of people interested in coins.  Some are avid collectors, others are just curious and would like to know about coins they have or may have inherited from family members. 

    ​Our course has been going for a number of years, with those attending enjoying the fun of learning and sharing information.  The variety of our monthly sessions ranges from exploring coins others bring along, knowing how to identify and value your coins, knowledge of new releases and discovering the vast array of information on coin YouTube channels.
