Some hidden riches might just be hiding in your change jar.

Most all of us have that change jar, old coffee can, or canister where we dump excess change.  But for some lucky folks, there might be some riches hiding in there.  Here is a list of eight valuable coins that might just be hiding among your pennies.

1. 2004 Wisconsin state quarter with extra leaf.  Value:  Up to $300.

Any old quarter from Wisconsin might buy you a phone call if you can find a phone booth.  But the 2004 quarter, which was part of the 50 State Quarters series, features a cow, an ear of corn and a wheel of cheese.  But some coins have an extra line below the front left leaf, which looks like another leaf entirely.  Look for those with the high leaf and low leaf.

2. 1995 double die penny.  Value: $20 to $50

With a double printed obverse (heads) side, it makes the words “liberty” and “In God We Trust” appear blurry.  This error also happened in 1969 and in 1972.

3. 1942-1945 silver nickel. Value: $.56 to $12.25

When the U.S. was at during WWII, the country needed to save as much nickel as possible for weaponry and ammunition.  So, it started minting nickels made of 35% silver.  It’s a federal offense to melt them down but finding one in good condition might put a few dollars in your pocket.

4. 1943 steel penny. Value: $.45 to $10

Just like reason for the silver nickel above, pennies were made from steel during war time.  This switch only lasted one year.

5. Ben Franklin half-dollar. Value:  $12 to $125

These coins with Ben Franklin and an eagle on them began circulating in 1948, which is ironic since Franklin strongly opposed using the bald eagle as the nation’s bird.  He thought the turkey was a much better representation.

6. 1932 – 1964 silver quarter. Value:  $7 to $65

During this time period, quarters were 90% silver and 10% copper.  While they look like any other quarter, they are worth more if they’re in the right condition.

7. “In God We Rust” 2005 Kansas state quarter. Value:  Up to $100

These coins are the result of grease which prevented a clean pressing.

8. President dollar coin with lettering errors. Value:  $20 to $45

In 2007, the U.S. Mint started printing dollar coins featuring U.S. presidents. Many of the early ones, especially those featuring George Washington, have incorrect or missing information on the edge of the coin.
