If something was worth 100000 dollars in 1971 what would it be worth today? It would cost more. Let's just say that cars back in the 1930s were about $1,000 because we didn't have the money that we have today. These dollars were made of copper and nickel, rather than silver, in most cases. If the S mark is there, check the sides of the coin--is it grey and copper, or darkish and lighter grey? If so, then it is likely 40% silver, and worth about $10 as of today.
