If you have three quarters, four dimes and four pennies, you have $1.19. You also have the largest amount of money in coins possible without being able to make change for a dollar.

A quarter has 119 grooves around the edge, and a dime has 118. Do you know the purpose of the ridges on the edges of coins? Without ridges, it is possible to scrape metal off coins without it being obvious. In the days when coins were made of silver or gold, a person could have made a good, but illegal, living from shaving coins and selling the precious metal.

Piggy banks began many years ago when people kept their money at home in jars made out of a type of clay called pygg. Over time they were molded into shapes like piggies and were called piggy banks.

Nickels, dimes, and quarters are pickled before they're minted...it might sound strange, but the blanks used to make these coins really are pickled. They're not soaked in vinegar though, like the pickled cucumbers you get on hamburgers. Instead, these copper-nickel blanks are soaked in a special chemical solution. This "pickling" washes and polishes the blanks.
