Most people know the saying “Born with a silver spoon”. This means that the child would never want for anything. Since the 17th century the silver spoon symbolizes great fortune and privilege and prosperous individuals would present them to newborns.
The ancient civilizations of Greece and Rome have known for thousands of years that silver had anti-bacterial properties and used silver to control bodily infections and prevent food spoilage. Early American settlers dropped silver coins into their milk to kill bacteria and to keep it fresh until use.
Throughout the “Middle Ages” in Europe, it had been noticed that royalty, who consumed most of their food and drink from silver tableware, utensils and cups, tended to develop a bluish skin tone (Blue bloods). That was due to the silver that entered their bodies during consumption.
Furthermore the lower rate of plague related deaths among royalty led to the inference that silver has protective properties.
