The dime coin has been in circulation since 1796. Dimes made before 1964 have a base value of the current price of silver. The most valuable dimes are measured by such standards as condition, rarity and date of the coins, and can be worth in excess of $2 million.
Coin collecting is often a hobby that people start when they are children, but coins can be valuable collectibles. There are a number of rare coins from the United States that are worth up to $10,000 or more.
