Older Coins made out of silver or copper are often worn almost completely smooth whether they are pulled out of the dirt or displayed in a museum.
You don't see old contemporary currency worn completely smooth, is it because silver and copper wear out more easily?
Then why aren't 40-year-old contemporary pennies worn smooth?
