The 1999-D Delaware Quarter is worth anywhere from $0.25 in circulated condition to over $600 in high-grade mint state. While most coins found in your pocket change are only worth face value, certain specimens with specific luster or errors can be quite valuable to collectors.
| Condition | Estimated Value |
|---|---|
| Circulated (Average) | $0.25 – $0.35 |
| Uncirculated (MS63) | $1.00 – $3.00 |
| Choice Uncirculated (MS65) | $10.00 – $25.00 |
| Gem Mint State (MS67+) | $150.00 – $650.00+ |
History of the 1999 Delaware Quarter
The 1999 Delaware State Quarter holds a special place in American numismatic history. It was the very first coin released under the 50 State Quarters Program, a ten-year initiative that revolutionized coin collecting for the general public. Because Delaware was the first state to ratify the Constitution on December 7, 1787, it earned the “First State” honors.
If you are looking to identify your finds, using a top coin identifier app can help you distinguish between the common releases and the rarer varieties. The Denver Mint (signified by the “D” mint mark) produced over 400 million of these coins, making them extremely common in everyday transactions across the United States.
However, just because they are common doesn’t mean every coin is the same. The design features Caesar Rodney on his historic 1776 horse ride to cast a crucial vote for Delaware in favor of American independence. Finding one of these coins in a pristine, “like-new” condition is much harder than finding a worn example, and that is where the real money lies for hobbyists using CoinKnow.

Grading and 1999-D Quarter Value Factors
The value of a 1999-D Delaware Quarter is almost entirely dependent on its grade. Professional grading scales run from 1 to 70. Most coins you find in your wallet are “Circulated,” meaning they have scratches, dullness, or smoothed edges. These are generally only worth their 25-cent face value, though they are great for starting a collection.

To reach prices above a few dollars, a coin must be in “Uncirculated” or “Mint State” (MS) condition. This means it has never been used for shopping and still retains its original “cartwheel” luster. For serious collectors, investigating the 1999 quarter value across different mint marks is essential to understanding the market.

| MS65 | Strong luster, very few marks | $15 – $30 |
| MS67 | Nearly perfect to the naked eye | $250 – $400 |
Comparison: Delaware 1999-D vs. 1999-P quarters
When checking your coins, you will notice either a “D” for Denver or a “P” for Philadelphia. Historically, the mintages (the number of coins made) dictate the rarity. For 1999, both mints produced hundreds of millions of coins. While the Denver Mint usually has a reputation for slightly better strikes, the values remain relatively parallel for average grades.
However, the “P” mint quarters occasionally see different price spikes at the highest professional tiers. You can compare the 1999-P Delaware quarter price trends to see how they stack up against your Denver coins. Many beginners use CoinKnow to track these fluctuations in real-time.
Prices for MS68 specimens—the highest grade usually found—can vary wildly. For Denver quarters, a high-grade registry set coin can easily break the $500 mark at auction, whereas a standard uncirculated coin might sit in a drawer for years without gaining much value.

Identifying Valuable 1999-D Quarter Errors
One of the most exciting ways to find a valuable 1999-D Delaware Quarter is to look for errors. Because these were the first coins in a massive new program, the mint sometimes ran into technical issues. Error hunters look for “die cracks,” “doubled dies,” or “off-center strikes.”
A common error to look for is the “Spitting Horse” variety. This occurs when a die crack forms near the horse’s mouth, making it look like the animal is spitting. While more famous on the Philadelphia coins, similar cracks can appear on Denver issues. If you find a coin where the image looks distorted or parts are missing, it could be worth significantly more than a standard quarter.
| Error Type | What to Look For | Est. Value |
|---|---|---|
| Off-Center Strike | Design not centered on the coin | $20 – $100 |
| Broadstruck | Coin is flatter and wider than normal | $15 – $50 |
| Die Crack | Raised lines across the design | $5 – $25 |
Where to Sell Your 1999-D Delaware Quarter
If you’ve used CoinKnow or a magnifying glass and determined that your 1999-D Delaware Quarter is in exceptional condition, you might be wondering where to sell it. For coins worth less than $10, local coin shops or eBay are your best bets. However, listing common quarters on eBay can be difficult due to shipping costs and seller fees.

For high-value coins (those graded MS66 or higher), professional auction houses like Heritage Auctions or GreatCollections are the preferred choice. These venues attract serious collectors who are willing to pay a premium for “top pop” (the highest known grade) coins to complete their sets.
Before selling, ensure your coin is protected. Putting a high-grade quarter in a PVC-free plastic flip or holder will prevent scratches and fingerprints from lowering its value. Even a single fingerprint can cause “toning” or corrosion over time, which often reduces the price collectors are willing to pay.

Q: How can I tell if my quarter is a “Denver” mint?
A: Look on the front side (obverse) of the coin, just behind George Washington’s ponytail. You will see a small letter “D” which stands for the Denver Mint.
Q: Is a silver 1999-D Delaware Quarter real?
A: No. The Denver Mint only produced copper-nickel clad quarters for circulation. If you have a silver version, it is likely a San Francisco “S” mint proof coin, or someone has plated a Denver coin with silver as a novelty, which actually ruins its collector value.
Q: Should I get my 1999 Delaware Quarter graded by PCGS or NGC?
A: Only if the coin appears to be in perfect, mark-free condition. It usually costs $30-$50 to grade a coin. Unless the coin is worth more than that, it is better to keep it in a simple coin flip.
