Bicentennial quarters are more than just coins—they’re part of American history. Minted in 1975 and 1976 to celebrate the United States’ 200th birthday, these quarters feature a unique design with a drummer boy on the reverse side.
While millions were produced, certain rare versions are highly prized by collectors.
However, many collectors make mistakes that can reduce the value of their coins. Let’s explore the top four mistakes and how to avoid them.
1. Misidentifying Rare Varieties
The Mistake
Not all Bicentennial quarters are valuable. Many collectors assume any quarter from 1975–1976 is rare, but this isn’t true.
How to Avoid It
Learn what to look for. Valuable varieties include the 1976-S Silver Proof Quarter and coins with minting errors like double dies (where the design appears doubled) or off-center strikes.
Missing these details could mean overlooking a coin worth hundreds—or even thousands—of dollars.
2. Cleaning the Coins
The Mistake
Many collectors think cleaning their coins will make them look better and increase their value.
Unfortunately, cleaning damages the coin’s surface, leaving scratches and dulling its natural finish.
How to Avoid It
Never clean your coins! Leave them in their original condition. Handle them carefully by their edges and store them in protective cases to keep them in the best shape.
3. Ignoring Mint Marks
The Mistake
Mint marks, which show where a coin was made, are often overlooked. Bicentennial quarters were minted in Philadelphia (no mint mark), Denver (D), and San Francisco (S).
Coins from San Francisco, particularly the 40% silver versions, are much rarer and more valuable.
How to Avoid It
Always check the mint mark, located on the obverse side of the coin near Washington’s profile. Knowing the mint mark can help you identify if your coin is a common issue or a valuable rarity.
4. Skipping Professional Grading
The Mistake
Collectors often skip professional grading, thinking it’s unnecessary. However, grading helps authenticate the coin, assess its condition, and determine its true market value.
Without grading, you might sell a valuable coin for much less than it’s worth.
How to Avoid It
Invest in professional grading from trusted services like PCGS or NGC. Graded coins are easier to sell and often fetch higher prices.
Plus, they come with certificates of authenticity, which increase buyer confidence.
Collecting Bicentennial quarters can be both fun and rewarding, but avoiding these common mistakes is essential to maximizing their value.
By learning to spot rare varieties, avoiding cleaning, paying attention to mint marks, and investing in grading, collectors can protect their treasures and unlock their full potential.
With a little knowledge and care, you could discover that your collection holds a piece of history worth far more than just 25 cents.
