Piggy banks find their origins in ancient times, when housewives used rustic containers made of soil to safekeep their savings. These were fondly called piggy jars and the name stuck even when soil was replaced by wood, metal and plastic, and the notion of a bank came into being. Although there is no known co-relation between pigs and saving habits, there is a lot of sense in the habit of piggy banks, which help kids appreciate the significance of savings, an invaluable learning that pays rich dividends throughout their lives.
