The back of this quarter shows Caesar Rodney on horseback, with the words "The First State". It belongs to the 50 State Quarters series, and so many were made that an ordinary one from your change is a common coin.
How to tell
Check these in order:
- Look at the date. The coin must say 1999 to be this quarter.
- Find the mint mark. A P means Philadelphia and a D means Denver. Only the P coin has the crack.
- If it is a P, look at the horse. Turn the back of the coin under a bright light and look at the horse's mouth.
- Look for a line running from the mouth. A crack that shows as a line from the horse's mouth, so the horse seems to spit, is the "spitting horse" error.
- Compare with a plain one. If the horse's mouth is clean, you have an ordinary coin.
Use a magnifying glass if you have one. A scratch or a bit of dirt can look like a crack, so look closely before you decide.
The spitting horse error
A die is the stamp that strikes the design into the coin. When a die cracks, the crack prints as a line on every coin it strikes afterward. On the 1999-P Delaware quarter, that line runs from the horse's mouth.
Dealers' price guides put a worn one at $5 to $10, but that figure is for coins a grading service has already graded. A coin from your change is almost certainly ungraded, and an ungraded coin usually sells for less. Its condition and the buyer decide what it actually sells for.
The ordinary coins
Philadelphia and Denver both made this quarter in huge numbers, so a 1999-P or 1999-D without the crack is worth face value. The coin holds no silver, so there is nothing to gain from its metal. Spend it or keep it as a souvenir of the series.
Condition
A worn coin is worth less than a sharp one. Look at the horse and rider: on a better-kept quarter the details are clear, and on a worn one they flatten out. Wear can also hide a die crack, so check a worn P coin carefully.
If you think you have the error and the coin looks good, a professional grading service such as PCGS or NGC can grade it. Grading costs money, so weigh that against the figure above before you send a coin.

Questions
Is every 1999 Delaware quarter valuable?
No. Nearly all of them are worth face value, whether from Philadelphia or Denver. Only a P coin with the spitting horse crack is worth more.
Can a Denver coin have the spitting horse error?
Price guides list this error on the Philadelphia coin only. A Denver coin is worth face value, so check the mint mark first.
Is it worth looking through other state quarters?
You can. See the 50 State Quarters guide, or read about the 2004 Wisconsin quarter and the 2005 Kansas quarter.
Where can I see other coins to check?
The guide to every US coin lists all the pages, from pennies to quarters.
