The 1999-S Delaware State Quarter is worth anywhere from $3 in lightly circulated condition to over $15 or more for high-grade proof examples — and certain cameo proof specimens can fetch even higher prices among dedicated collectors. If you’ve come across one of these coins in your collection or in an old folder, you’re in the right place to find out exactly what it’s worth.
What Is the 1999-S Delaware State Quarter?
The 1999-S Delaware State Quarter holds a special place in American coinage history. It was the very first coin released under the 50 State Quarters Program, honoring Delaware’s nickname as “The First State.” The “S” mint mark tells you it was struck at the San Francisco Mint, which produced proof versions of these quarters exclusively for collectors — not for everyday circulation.
Because these coins were made as proof strikes, they feature sharp, mirror-like fields and finely detailed designs. The reverse shows Caesar Rodney on horseback, commemorating his famous midnight ride to vote for independence.
If you’re not sure whether the coin in your hand is a proof or a regular strike, using a coin identifier and value app can help you quickly identify the type and condition without needing expert knowledge. These tools are especially useful for everyday people who aren’t seasoned numismatists.

Factors That Affect the Value of Your 1999-S Delaware Quarter
Not every 1999-S Delaware Quarter is worth the same amount. Several key factors influence what a collector or dealer will be willing to pay.

Cameo contrast is one of the biggest value drivers. Proof coins with frosted devices set against mirror-like backgrounds earn “Cameo” or “Deep Cameo” designations from grading services, and these coins are significantly more valuable than standard proof examples.
Silver vs. clad composition also matters a great deal. Silver proof quarters contain 90% silver, which not only adds intrinsic metal value but also tends to display better contrast and detail — both things collectors love.
Professional grading can dramatically increase buyer confidence. A coin slabbed and graded by PCGS or NGC in PR-69 or PR-70 Deep Cameo can sell for several times the price of an ungraded example. If you believe your coin is in exceptional condition, it may be worth the cost of having it professionally evaluated.

The original packaging also helps. Many 1999-S proof coins were sold in U.S. Mint proof sets, and coins that remain in their original holders with the accompanying set tend to retain collector interest.

FAQ
Q: How many 1999-S Delaware State Quarters were minted?
A: The U.S. Mint produced approximately 3.7 million clad proof versions and around 804,000 silver proof versions of the 1999-S Delaware State Quarter. The lower mintage of the silver proof makes it more desirable to collectors.
Q: Is my 1999-S Delaware Quarter made of silver?
A: It depends on which proof set it came from. If your coin came from a standard clad proof set, it contains no silver. If it came from the Silver Proof Set, it is composed of 90% silver. You can check the edge of the coin — a silver proof will show a uniform silver edge with no copper stripe.
Q: Should I clean my 1999-S Delaware Quarter before selling it?
A: No — never clean a coin before selling or having it graded. Cleaning removes the original surface and almost always lowers the coin’s value significantly in the eyes of collectors and grading services. Keep your coin as-is and store it in a protective holder instead.
