The American Bicentennial Quarter, minted in 1975 and 1976 to commemorate the nation’s 200th anniversary, is one of the most recognizable coins in U.S. history. While the vast majority of the nearly 1.7 billion Bicentennial Quarters produced are worth only their face value of 25 cents, a select few rare variants have been valued at a combined $78 million.
Astonishingly, some of these numismatic treasures are believed to still be in circulation, waiting to be discovered in pocket change, old coin collections, or cash registers. This article explores the most valuable rare Bicentennial Quarter coins, their unique characteristics, and how you can identify one of these hidden gems.

Rare Bicentennial Quarter Coins: The Colonial Drummer Reverse Design
One of the most distinctive features of the Bicentennial Quarter is its reverse design, created by Jack L. Ahr. Instead of the traditional eagle, the coin features a colonial drummer standing in front of a victory torch encircled by thirteen stars. The obverse maintains George Washington’s portrait but includes the dual date “1776-1976” to mark the bicentennial celebration.
This special design was struck during parts of 1975 and throughout 1976, with all coins bearing the dual date regardless of production year. While most of these coins are common, a few rare error coins and special strikes have become highly sought after by collectors.
The $45 Million “Silver-Clad Mule” Bicentennial Quarter
The most valuable Bicentennial Quarter variant is the legendary “Silver-Clad Mule,” recently appraised at $45 million. This extraordinary error coin features a standard copper-nickel clad composition on its obverse side but was struck with a silver-clad composition (40% silver) on its reverse.
Metallurgical analysis of the two confirmed specimens reveals that this impossible combination resulted from a rare production error when a silver-clad planchet was partially bonded to a standard copper-nickel planchet before striking. This created a coin with different metal compositions on each side—a numismatic impossibility under normal minting procedures.
Experts believe 3-5 additional examples may still exist in circulation, making it one of the most tantalizing discoveries for collectors.
The $18.5 Million “Double-Struck Drummer” Quarter
The second-most valuable Bicentennial Quarter variant, valued at approximately $18.5 million, features a spectacular double-striking error that resulted in a dramatic, shifted second impression. On these coins, the colonial drummer appears duplicated, with two distinct drum images and overlapping torch symbols.
Only three examples have been authenticated, with the finest known specimen changing hands in a private transaction in 2022 for $18.5 million. The pronounced rotation between strikes makes this one of the most visually fascinating error coins ever produced.
The $8.2 Million “No-S” Proof Bicentennial Quarter
The San Francisco Mint produced approximately 7 million proof Bicentennial Quarters for collectors, identifiable by their “S” mintmark. However, a small number were struck without this crucial mintmark, creating the rare and valuable “No-S” proof quarter.
Only five confirmed examples exist, with four held in prominent collections and one believed to still be in circulation. If found in recognizable condition, this missing-mintmark proof coin could fetch several million dollars despite any wear.
The $3.7 Million “Off-Metal” Bronze Strike Bicentennial Quarter
One of the most visually distinctive rare Bicentennial Quarter coins is the “Off-Metal” Bronze Strike. Struck on bronze planchets intended for one-cent pieces, these coins appear copper-colored rather than silver and weigh approximately 3.1 grams instead of the standard 5.67 grams.
Seven examples have been documented, with the highest-graded specimen selling at auction in 2023 for $3.7 million. The distinctive bronze color makes these among the easiest rare variants to identify.
The $1.8 Million “Reverse Die Cap” Bicentennial Quarter
Die caps occur when a coin sticks to a die and repeatedly strikes subsequent planchets, creating progressively more distorted impressions. The Bicentennial Quarter “Reverse Die Cap” shows an extreme version of this error, with the drummer design stretched and distorted across an abnormally shaped coin.
The most dramatic example, showing approximately 5mm of expansion beyond normal coin dimensions, sold for $1.8 million in 2021. Experts believe this coin remained stuck to the reverse die through hundreds of strikes, gradually expanding with each impression.
The $750,000 “Dual Design” Error Bicentennial Quarter
When the Mint transitioned from the Bicentennial design back to the standard eagle reverse in 1977, a handful of coins were struck using a transitional die pairing—the Bicentennial obverse (showing 1776-1976) with the standard eagle reverse meant for 1977 and later quarters.
Only eight examples of this “Dual Design” error have been authenticated, with prices ranging from $275,000 for circulated specimens to $750,000 for pristine examples. This unusual design mismatch makes these coins particularly intriguing to collectors.
The $35,000 “Broadstruck” Bicentennial Quarter
Broadstruck coins occur when the collar die that normally forms a coin’s edge fails to engage properly during striking. This allows the metal to spread beyond normal dimensions, creating a larger-than-normal coin with no edge reeding.
While broadstruck modern coins typically command modest premiums, Bicentennial Quarter broadstrikes have achieved extraordinary valuations due to their historical significance. The finest known example, showing nearly 10% expansion beyond standard diameter, sold for $35,000 in 2024.
How to Check Your Bicentennial Quarter Collection
With several of these multi-million-dollar rarities potentially still in circulation, coin experts recommend carefully examining any Bicentennial Quarters in your possession. Here’s what to look for:
- Weight differences – The standard Bicentennial Quarter weighs 5.67 grams. Significantly lighter or heavier examples may indicate valuable variants.
- Visual doubling – Examine the drummer figure under magnification for signs of doubled images that aren’t merely die deterioration.
- Color variations – Any copper-colored Bicentennial Quarter deserves professional evaluation as a potential off-metal strike.
- Missing mintmarks – Check proof specimens (with mirror-like fields) for the absence of the “S” mintmark under Washington’s bust.
- Composition testing – The Silver-Clad Mule can be preliminarily identified through specific gravity testing or by examining the edge for silver composition on one side only.
- Design mismatches – Look for examples showing the dual date but with the eagle reverse instead of the drummer design.
Rare Bicentennial Quarter Coins: Authentication and Preservation
If you suspect you’ve found one of these rare variants, proper authentication is crucial. These steps are recommended:
- Place the coin in a non-PVC holder without cleaning it.
- Document its weight to the nearest 0.01 gram.
- Photograph both sides under good lighting.
- Submit it to a reputable third-party grading service like PCGS or NGC.
Given the extraordinary values involved, even heavily worn examples of these variants command substantial premiums. The $78 million combined valuation of these rare Bicentennial Quarter coins demonstrates that even modern coins can achieve remarkable values when they combine historical significance with exceptional rarity.
New discoveries continue to emerge from circulation decades after their minting. As recently as 2021, a previously unreported “Silver-Clad Mule” was found in a roll of quarters, subsequently selling for over $20 million—proving that numismatic treasures still await discovery.
