Why are so many coin banks shaped like pigs? Why not dogs or cats or elephants?
Coin banks weren always made to look like pigs. In fact, the name piggy bank may have come from a kind of clay and not from the animal at all.
The history of the piggy bank goes back to the Middle ages. At that time in Western Europe, metals were expensive, so a cheap orange clay known as pygg was used for everyday items such as dishes and jars. In fact something made from pygg clay was often just called a pygg. The first piggy bank may well have been a pygg in which a person put a few extra pennies to buy a treat on market day.
People have always had a hobby of saving pennies, and using a pygg as a coin bank became common practice. Potters (陶工) began making jars specially for saving coins, and eventually these jars took a pig-like shape. Modeling a bank to look like a pig may have been influenced by the name of the clay. The earliest Roman coin bank ever found was decorated with a pig. Because it was considered as a valuable farm animal in many countries, the pig was an appropriate symbol of wealth and prosperity.
These early clay banks were fragile and easily broken. As time passed, mining became less expensive. Iron, copper, and silver gradually replaced pygg clay in the production of household items. Although pygg clay lost its popularity, the habit of saving pennies did not. Today piggy anks are made of every material imaginable.
The familiar saying A penny saved is a penny earned is as old as the clearly piggy banks. Marry a child received his or her first coin bank accompanied by this wise advice. The modern-day piggy bank may have changed in sine, shape, and spelling, but it saves our pennies just as well as the first pygg did countries ago.
