Production totals by mint and composition

Standard Circulation Quarters (Copper-Nickel Clad)

Most Bicentennial quarters found in circulation are worth their face value of 25 cents. However, those in pristine, uncirculated condition can be worth more to collectors:

Silver Composition Quarters

The silver varieties were not released for circulation but sold directly to collectors in special mint sets. These quarters generally command higher premiums:

1. Double Die Errors

Double die errors occur when the die used to strike the coin receives a double impression during its creation, resulting in doubled design elements on the struck coins. These can be quite valuable, with prices ranging from market-dependent values for minor doubling to several hundred dollars for prominent examples.

2. Off-Center Strikes

When a coin is struck while not properly centered between the dies, it creates an off-center strike. The value depends on the severity of the off-centering and whether the date and mint mark are still visible:

• a category-dependent range off-center: market-dependent values
• a category-dependent amount off-center (with date visible): market-dependent values
• a category-dependent range off-center (with date visible): market-dependent values+

3. Double Denomination Errors

One of the most valuable Bicentennial quarter errors is the double denomination error, where a quarter is struck over another denomination coin. A Bicentennial quarter struck on a dime planchet sold for market-dependent values at auction, making it one of the most valuable modern error coins.

4. Silver Proof Errors

The most valuable Bicentennial quarters are generally rare error coins in the silver proof series:

1. Mint Mark: All silver Bicentennial quarters have an “S” mint mark (San Francisco)
2. Weight: Silver quarters weigh approximately 5.75 grams vs. 5.67 grams for clad
3. Edge Examination: The edge of a silver quarter will not show the copper core visible on clad quarters
4. Original Packaging: Many silver quarters were sold in special Treasury Department packaging
5. Tone and Color: Silver quarters often have a slightly different color tone than clad versions

It’s important to note that not all “S” mint mark quarters are silver - San Francisco also produced clad proof versions. The most reliable method is checking the edge for the absence of a copper core layer.

1. Local Coin Dealers: Professional numismatists can appraise and purchase your coins. They typically offer less than retail value but provide immediate payment.

2. Online Marketplaces: Platforms like eBay allow you to reach a wide audience of collectors. However, you’ll need to handle shipping and may encounter fees.

3. Coin Shows: These events bring together dealers and collectors, providing multiple potential buyers for your coins.

4. Online Coin Forums: Sites like CoinTalk have marketplaces where you can connect with collectors interested in Bicentennial quarters.

5. Auction Houses: For extremely rare or valuable error coins, specialized numismatic auction houses may be your best option to maximize value.

For common Bicentennial quarters in average condition, it’s often best to hold onto them as interesting historical pieces rather than selling them for face value.

To identify a silver Bicentennial quarter:

Check for an "S" mint mark under Washington’s neck
Examine the edge - silver quarters won’t show a copper core like clad quarters
Weigh the coin - silver quarters weigh 5.75 grams vs 5.67 grams for clad
Look for original government packaging, as silver quarters were only sold in special sets

Remember that not all "S" mint quarters are silver, as San Francisco also produced clad proofs.

For the average collector, Bicentennial quarters represent an accessible and historically significant part of American numismatic history. Their distinctive design commemorating the nation’s 200th birthday makes them worth keeping regardless of monetary value.

If you believe you have a potentially valuable Bicentennial quarter, consider having it professionally evaluated by a reputable coin dealer or third-party grading service. This will provide you with a definitive assessment of its attribution evidence, condition, and market value.

Whether your Bicentennial quarters are worth face value or hundreds of dollars, they remain an important piece of American coinage history that connects us to the celebration of the nation’s bicentennial.
