1976-S Bicentennial, Silver

San Francisco's silver Bicentennial half is the only 40% silver-clad business strike of the entire 1776-1976 commemorative program, distinct from both the cupronickel circulation issues and the silver proof. Composition reverts to the silver-clad recipe used 1965 through 1970: outer layers of 80% silver and 20% copper bonded to a core of 20.9% silver and 79.1% copper, averaging 40% silver overall, with a finished weight of 11.50 g and an actual silver weight of 0.14792 troy ounces. The dual-dated obverse keeps Roberts's Kennedy portrait, the reverse carries Seth Huntington's Independence Hall, and the S mintmark sits above the date on the obverse. The 11,000,000 mintage was struck for the three-coin Bicentennial Silver Uncirculated Set, packaged alongside the silver Bicentennial quarter and silver Bicentennial Eisenhower dollar in a red cardboard envelope with a blue acrylic display sleeve.

The set was sold by the Mint from 1975 through 1986, when remaining inventory was discounted and finally exhausted. As a result, original packaging still surfaces in quantity today, and intact red envelopes with all three coins are easy to find. Loose silver halves trade at a modest discount to packaged examples, since collectors building Bicentennial set runs prefer the original presentation. Strike quality on this coin runs noticeably better than the Denver and Philadelphia clad issues: San Francisco's lower production volume allowed cleaner die management, and Independence Hall's clock face, columns, and roofline come up sharply on most examples. Bag marks remain the grading limiter, especially on Kennedy's cheek and the wide reverse fields, but MS66 and MS67 pieces are far more plentiful here than on the clad Bicentennials.

For collectors this issue functions as both a numismatic and a small bullion holding, with intrinsic silver content tracking the spot price. Type-set buyers acquire it for the silver-clad composition alone, since no other 40% silver business strike was issued after 1970. Bicentennial set builders chase original packaging in pristine condition. Authentication is straightforward: weight and specific gravity sort the silver coin from any clad attempt, and the S mintmark distinguishes it from the Philadelphia and Denver issues. Premiums step up at MS67 and become serious at MS68, where the certified population thins quickly.
