1999-D Delaware State Quarter Value: Price & Errors Guide

The 1999-D Delaware Quarter is worth anywhere from its face value of $0.25 in worn condition to over $3,000 for rare “Spitting Horse” error varieties in high grades. While most circulated coins are worth just twenty-five cents, certain mint-state specimens and unique production errors can be a significant find for any casual collector.

History of the 1999-D Delaware Quarter Dollar

The Delaware Quarter holds a special place in American numismatic history as the very first coin released in the 50 State Quarters Program. This ambitious project, which ran from 1999 to 2008, aimed to honor each state in the order they joined the Union. Delaware, having ratified the Constitution first on December 7, 1787, naturally led the charge.

If you’ve recently found one of these in your pocket change and want to know more about it, using a free coin identifier app can help you confirm the mint mark and design details instantly. The reverse of the coin depicts Caesar Rodney’s historic 1776 horseback ride to Philadelphia to cast a tie-breaking vote for independence.

The “D” mint mark indicates that the coin was struck at the Denver Mint. Because these were produced in massive quantities for general circulation, they are incredibly common. However, the 1999-D is particularly interesting to collectors because it was the first year of the series, and many people began their collection journey with this exact coin. You can often track the rising market value for 1999 Delaware quarters as collectors look to complete full sets of registry-grade coins.

Whether you are a seasoned collector or a casual observer, the CoinKnow app is a fantastic resource for checking the latest market trends. Identifying the nuances between a common pocket find and a high-value specimen is easier when you have the right tools at your fingertips.

Determining the Condition and Grade of Your 1999-D Quarter

When assessing the value of a 1999-D Delaware Quarter, condition is everything. Most of the quarters you find in your spare change are “circulated,” meaning they have been used in commerce and show signs of wear like scratches, smoothed-out details on the horse’s mane, or a dull luster.

To fetch a premium price, a coin must be in “uncirculated” or “Mint State” (MS) condition. This means it has never been spent and retains the original shine it had the day it left the Denver Mint. Professional grading services like PCGS or NGC use a 70-point scale to determine quality. For a standard 1999-D, you generally need a grade of MS67 or higher to see values climb into the double or triple digits.

For those trying to determine if their coin is worth sending in for professional grading, CoinKnow offers high-resolution image comparisons. Remember, most modern quarters are not worth the grading fee unless they appear absolutely perfect to the naked eye.

The “Spitting Horse” Error – The Most Famous 1999-D Variety

If you want to find real money in your change jar, you need to look for the “Spitting Horse” error. This is a famous die clash variety found specifically on the 1999 Delaware quarters. It occurs when the obverse (heads) and reverse (tails) dies strike each other without a coin blank in between, causing a small crack or indentation on the die.

On the 1999-D, this manifests as a raised line coming from the horse’s mouth, making it look like the animal is spitting. Depending on the severity of the line and the overall condition of the coin, this error can sell for $10 to $20 in circulated condition and significantly more in high grades.

Identifying these errors can be tricky for the untrained eye, but it is one of the most rewarding parts of “coin roll hunting.” You can find detailed 1999 Delaware error coin values by looking at recent auction records from major sites. While thousands of these were likely made, they remain a favorite among collectors of modern errors.

Mintage Numbers and Scarcity

The Denver Mint produced a staggering 373,400,000 Delaware Quarters in 1999. Because nearly 400 million were made, the “D” mint mark version is not considered rare in a general sense. However, scarcity is relative in the world of coin collecting.

While the total mintage is high, the number of coins that survived in “perfect” condition (MS68 or MS69) is incredibly low. Most quarters were tossed into bags, slammed into other coins, and sent into the rough world of circulation. This mechanical handling creates “bag marks,” which are tiny nicks that lower the grade.

As the table shows, Denver actually produced fewer Delaware quarters than Philadelphia, though both are abundant. If you are looking to build a high-value collection, focusing on the Denver strikes with heavy luster is a smart move. Using an app like CoinKnow can help you keep track of your inventory and see which mint marks you are missing.

Other Potential Rare Errors to Watch For

Aside from the Spitting Horse, the 1999-D Delaware Quarter is prone to other common minting errors. These include off-center strikes, where the design is pushed to one side, and clipped planchets, where the coin looks like a “bite” was taken out of the edge.

Another rare but valuable error is a “struck on the wrong planchet” error. Occasionally, a quarter design is struck on a dime or nickel blank. These are extremely rare and can be worth thousands of dollars. Always check the weight and diameter of your coins if something looks “off.”

Grease strikes are also common in the 1999 series. This happens when grease fills the die, causing some of the letters or numbers to look faint or disappear entirely. While “faded” coins are sometimes just worn, a true grease strike will have a smooth surface where the metal should have been. These are generally oddities rather than big-money items, but they are still fun conversation pieces.

Summary: Should You Keep Your 1999-D Delaware Quarter?

For most people, a 1999-D Delaware Quarter is simply worth twenty-five cents. If you find one in your change, it’s likely a well-circulated coin that has seen years of use. However, if you find one that looks brand new, or if you spot a raised line on the horse’s neck (the Spitting Horse), it is definitely worth setting aside.

The State Quarter program changed the way Americans look at their change. It turned millions of people into casual collectors. Whether you’re looking for financial gain or just want to complete a map of all 50 states, understanding the value of your coins is the first step. For the best results, use modern technology and historical data to ensure you don’t accidentally spend a small fortune at the vending machine.

FAQ

Q: How can I tell if my 1999 Delaware Quarter is the “Spitting Horse” version?

A: Look closely at the reverse side (the side with the horse). Examine the area around the horse’s mouth. If you see a thin, raised line of metal extending downward from the mouth toward the ground, you likely have the Spitting Horse die clash error. This is not a scratch (which would be indented), but a raised line.

Q: Why is the 1999-D more or less valuable than the 1999-P?

A: Generally, the P and D mints have similar values. However, the 1999-D is often sought after in higher grades (MS67 and MS68) because the strike quality at the Denver Mint that year was sometimes superior or produced fewer high-grade survivors compared to Philadelphia.

Q: Is there a silver version of the 1999-D Delaware Quarter?

A: No. Silver proof quarters were minted in 1999, but they were only produced at the San Francisco Mint and bear the “S” mint mark. All 1999-D quarters are made of a copper-nickel clad composition (copper core with a nickel-copper outer layer).

Q: What is the highest price ever paid for a 1999-D Delaware Quarter?

A: High-grade specimens have sold for several hundreds of dollars in professional auctions. In some cases, a 1999-D Delaware Quarter graded MS68 by PCGS has reached prices between $400 and $600. Major errors, like off-center strikes, can exceed this amount.
