Assuming it's from circulation, 25 cents unless it is one of a small number of rotated die errors that occurred with that particular design. The rotated die error is characterized by both sides of the coin pointing the same direction; that is, Caesar Rodney's head on the reverse points to the same spot on the coin's rim as does the top of Washington's head on the front. Don't be confused if the back seems to be "upside down", that's the way all U.S. coins are supposed to be struck - compare with another quarter of a different date if you're unsure. The rotated die error is fairly rare so it's not likely that you would have one pulled from pocket change, however.
A 1999-S Delaware Silver Proof Quarter, certified as a PR-70 Deep Cameo example has a listed retail value of $3,000.00.
Its value could range from $25 to $150 depending on how far off center it is.
The 1999-S silver proof quarters are about $8.00.
It depends on the degree of rotation, the farther off center it is the more value it has. Take it to a dealer or collector for an assessment.
The top date of 1787 makes it a Delaware, Pennsylvania, or New Jersey quarter, all of which were actually minted in 1999. The coin is worth 25 cents.
25 cents
Did you look under the horse? It's dated 1999, the year the coin was struck. 1787 is the year Delaware became the First State.
The quarter probably says "Ceasar Rodney" below the horse's head, because it's a 1999 Delaware state quarter. It's worth 25 cents.
Those are the letters WC, the initials of William Cousins, who designed the Delaware quarter.
$12.50!
If you found it in change, 25¢. All state quarters (1999-2008) were minted by the carload and have no extra value when they're in circulated condition
My 1999 S Delaware quarter has the word "COPY" imprinted over Washingtons head on the front and the back design has United States of America and E Pluribus Unum across the top. Caeser Rodney rides East not West and Has the state of Delaware behind him. To the upper left of that is the date of 1787 and below states Delaware Quarter Dollar. I also have a 2004 S Washington D.C. with the same "COPY" over Washington's head and a picture of the White House and Washington Monument on the back. These were my grandpa's quarters and hes passed away now so I cant ask him about them. Searched for 2 hours online and found nothing.
