If you have you ever wondered why coins have a musty, metallic odor after they have handled them for awhile, you're about to find out the answer? You may have assumed that the smell came from the coins being dirty, but in reality the smell isn't from the coins at all - it's from you. That's right. That smell is your own body odor. According to a recent scientific study, the metallic odor comes from a breakdown of oils in your skin after your touch coins and not from the coins themselves.
During the experiment for the study, researchers took gas samples from skin when people reported smelling the metallic odor after touching iron. The smell was then traced to an organic molecule called 1-octen-2-one which is formed when certain oils in skin decompose. The researchers believe that when a person touches an object made of iron, the perspiration from their skin causes the iron atoms to gain two electrons. These iron atoms then react with oil in skin forming 1-octen-2-one and causing the smell.
