Do coins burn a hole in your pocket? At some point in their manufacturing process, they certainly could. Hard to believe, but thermal processing plays multiple roles in the manufacture of the coins we use every day.
The earliest coins may have been made during the 600s B.C. in Turkey. Many historians believe they were also invented independently in ancient China and India. Early colonists in this country used any foreign coin they could get. The most commonly used was the large Spanish dollar called “pieces of eight”. To make change, the coin would be chopped into eight pie-shaped pieces called bits. Two bits were worth a quarter of a dollar - hence the term still in use today. Coins today have government-approved designs stamped in them much as they did in ancient times. U.S. coins must all contain the following words: “In God We Trust,” “United States of America” and “E Pluribus Unim”.
