1979 Washington Quarter Value Guide: Rare Errors, Mint Marks and Collector Prices Explained

1979 Washington Quarter Value Guide: The Washington Quarter has been a cornerstone of American coinage since 1932, when it was first introduced to commemorate George Washington’s bicentennial. By 1979, the design had already been in circulation for nearly fifty years, yet collectors continue to find fascination in this particular year. While most quarters from 1979 may appear ordinary, subtle details such as mint marks, condition, and rare errors can transform a seemingly common coin into a prized collectible. The 1979 Washington Quarter is especially notable because it represents the final year when Philadelphia-minted quarters carried no mint mark, a detail that adds historical significance.

Historical Background

The late 1970s were a period of economic change in the United States. Inflation was rising, silver had long been removed from quarters, and the Mint was experimenting with new proof varieties. The 1979 Washington Quarter reflects these shifts. Struck in copper-nickel clad composition, the coin features Washington’s profile on the obverse and an eagle perched on a bundle of arrows on the reverse. Collectors value this year not only for its role in the series but also for the unique minting quirks that make certain examples rare and desirable.

Mint Marks and Their Importance

Mint marks are small letters on coins that indicate where they were produced. For the 1979 Washington Quarter, three primary mint marks exist:

  • No Mint Mark (Philadelphia): These coins were struck at the Philadelphia Mint. 1979 was the last year Philadelphia quarters carried no mint mark, making them historically significant.
  • D Mint Mark (Denver): Coins struck in Denver carry a “D” mint mark. These are common but can be valuable in high grades.
  • S Mint Mark (San Francisco): Proof coins were struck in San Francisco, with two distinct varieties known as Type 1 and Type 2.

Understanding mint marks is crucial because they directly influence rarity and value.

Collector Value by Condition

The value of a 1979 Washington Quarter depends heavily on its condition. Circulated coins are generally worth face value, but uncirculated and proof examples can command much higher prices. Below is a table summarizing typical values across grades and mint marks.

Rare Errors and Varieties

Error coins are among the most exciting finds for collectors. The 1979 Washington Quarter has several notable varieties:

  • Off-Center Strikes: Coins struck off-center can range in value depending on how dramatic the error is. A 50 percent off-center strike can fetch hundreds of dollars.
  • Double Die Obverse: Some quarters show doubling in Washington’s profile or inscriptions. These are rare and highly collectible.
  • Clipped Planchets: A clipped planchet error occurs when part of the coin’s edge is missing. Values vary but can exceed $100.
  • Proof Type 1 vs. Type 2: The San Francisco Mint produced two proof varieties. Type 1 has a blurry “S” mint mark, while Type 2 has a clearer, sharper “S.” Type 2 proofs are scarcer and more valuable.

Factors That Influence Value

Several factors determine the value of a 1979 Washington Quarter:

  • Condition: Coins graded by professional services such as PCGS or NGC carry higher premiums.
  • Rarity: Errors and proof varieties are rarer than regular strikes.
  • Historical Significance: The last year of no mint mark from Philadelphia adds collectible appeal.
  • Market Demand: Coin values fluctuate based on collector interest and market trends.

Collecting Strategies

For collectors, the 1979 Washington Quarter offers multiple avenues of interest. Beginners may start by collecting circulated examples from pocket change, while advanced collectors seek high-grade proofs or rare errors. Building a complete set of 1979 quarters from all mints, including both proof types, is a rewarding challenge. Many collectors also enjoy searching rolls of quarters from banks, hoping to uncover hidden gems.

Investment Potential

While most 1979 quarters are not worth more than face value, rare varieties and pristine examples can appreciate significantly. Coins graded MS-67 or higher are scarce and often sell for hundreds of dollars. Proof Type 2 quarters in PR-70 condition are especially desirable, with values reaching into the hundreds. As with all collectibles, investment potential depends on rarity, condition, and long-term demand. Collectors who focus on quality and rarity tend to see the best returns.

Conclusion

The 1979 Washington Quarter may appear ordinary at first glance, but its historical significance, mint mark variations, and rare errors make it a fascinating coin for collectors. Whether you are searching through pocket change or building a high-grade collection, understanding the nuances of this coin can help you uncover hidden value. For many numismatists, the 1979 quarter represents not just a piece of currency but a tangible link to America’s coinage history.
