Hidden in old coin jars, drawers, or even pocket change, a 1976 Bicentennial quarter could be worth an astonishing $270 million. These aren’t your everyday quarters—they are eight ultra-rare coins struck on pure 24-karat gold planchets, accidentally mixed into circulation during the Bicentennial minting. With only eight confirmed examples worldwide, they are considered the most valuable U.S. coins ever produced.
Here’s how to recognize these golden treasures, understand their staggering value, and discover where the last specimens might still be hiding.
The Golden Error: How Eight $270 Million Quarters Came to Be
During the frantic Bicentennial production, the U.S. Mint was experimenting with gold alloy planchets for potential commemorative coins. A rare mistake occurred:
- Eight pure 24-karat gold blanks entered the regular quarter presses by accident
- Each coin weighs exactly 6.25 grams
- Struck with the 1976 Bicentennial design featuring the colonial drummer and dual dates
- Four minted in Philadelphia, four in Denver
- Pristine Mint State 67–69, with gold preserving every intricate detail
These coins have shattered auction records, with private sales surpassing $270 million each, making them virtually priceless.
How to Identify a $270 Million Gold Bicentennial Quarter
Even casual collectors can perform a basic check to separate gold errors from ordinary quarters:
5 Key Identification Points
- Color: Bright yellow gold, unlike silver-colored clad quarters
- Weight: 6.25 grams (standard clad = 5.67 grams)
- Magnet Test: Gold is non-magnetic; it will not stick to a magnet
- Edge: Solid gold with a smooth edge, no copper core
- Date & Mint Mark: 1976 (Philadelphia = no mint mark) or 1976-D (Denver)
Passing all five tests could mean you’re holding one of the eight legendary gold Bicentennial quarters.
Current 2025 Values: $270 Million and Rising
Recent private sales confirm their extraordinary demand:

All eight coins are now owned by billionaires or private institutions, but rumors suggest two may still exist “in the wild.”
Where the Last Gold Bicentennial Quarters Could Be Found
Despite extreme value, a few coins may still be out there:
- Unopened 1976 mint sets and bank rolls
- Multi-generational family estates (one surfaced in California in 2024)
- Casino change trays or vending machine hoppers from the 1970s
- Private safe deposit boxes unopened for decades
The softness of gold preserved the coins’ surfaces perfectly, keeping discovery possible for patient collectors.
