How do prove to your friend that penny is not gold?
For one thing, no circulating pennies anywhere were ever made of gold, apart from some printed in Ancient Rome, which are antiques and rare to find today. If your friend doesn't believe that, you can buy a relatively cheap home gold testing kit. The kit consists of an acid used to detect gold and special magnet. The more expensive versions, which are designed for experts rather than amateurs, may also include digital scales, acids for silver and platinum as well as gold and a small sample of a gold nugget to practice with. You'll find these online in places such as Amazon.
