With counterfeits flooding the market, knowing the specific diagnostic points for this item is critical. The 1976 Bicentennial Silver Uncirculated Set Souvenir Set represents a unique moment in American numismatic history, combining the patriotic celebration of America’s 200th birthday with special coinage and commemorative medals.
Identifying Key Markers
Weight Verification
Authentic 1976 Bicentennial silver uncirculated sets contain coins with specific weight specifications. The 40% silver-clad coins should weigh:
- Quarter: 6.25 grams
- Half Dollar: 11.50 grams
- Dollar: 24.59 grams
Use a precision scale accurate to at least 0.01 grams. Significant deviations from these weights indicate potential counterfeits.
Magnetic Properties Test
Authentic 40% silver-clad Bicentennial coins are not magnetic. Use a strong neodymium magnet to test each coin. If any coin exhibits magnetic attraction, it’s a clear indication of a counterfeit made with magnetic base metals.
Die Markers and Design Details
Examine the following die markers carefully:
- Check the sharpness of the drum on the quarter’s reverse
- Verify the detail in Independence Hall on the half dollar
- Examine the lettering sharpness on all three denominations
- Look for the “S” mint mark on each coin (indicating San Francisco Mint origin)
