What counts as half dollars?
The US half dollar runs in a nearly unbroken line from 1794: Flowing Hair and Bust halves, Seated Liberty, Barber (1892–1915), the beloved Walking Liberty (1916–1947), Franklin (1948–1963) and Kennedy (1964 to date). The composition timeline matters as much as the design: halves are 90% silver through 1964, 40% silver from 1965 to 1970, and copper-nickel clad from 1971 onward — with silver returning only in special collector issues.
Step-by-step: identifying half dollars
You need good light, a digital scale that reads to 0.1 g, calipers if you have them, and a 5x–10x loupe. With those on hand, here is how to identify half dollars:
- Identify the type by design and date — Barber, Walking Liberty, Franklin or Kennedy for 20th-century coins.
- Apply the composition timeline: dated 1964 or earlier means 90% silver, 1965–1970 means 40% silver, 1971 onward is clad (except collector issues).
- Find the mint mark: on Kennedys it moved to the obverse below the bust in 1968; earlier types carry it on the reverse.
- Weigh in doubt: 90% halves weigh 12.50 g, 40% halves 11.50 g and clad halves 11.34 g — enough spread for a kitchen-grade scale.
- On Franklins, examine the Liberty Bell for Full Bell Lines (FBL), a strike-quality designation that multiplies mint-state value.
- Check Walking Liberty key dates: 1916, 1916-S, 1921, 1921-D and 1938-D lead the series.
Are half dollars valuable?
Silver halves have a hard floor at melt — a 90% half contains about a third of an ounce of silver — while common clad Kennedys are worth exactly fifty cents. Collector value concentrates in high-grade Walkers and Barbers (strong four-figure prices for gems of better dates), FBL Franklins, and early key dates; circulated common silver halves trade as bullion with a small premium.
Treat any figure you read as a starting point rather than a quote. What a specific piece brings depends on its grade, its rarity and its eye appeal, and the only reliable comparison is recent sold results for equivalent examples — exactly the data CoinVault Pro’s live values are built on.
Common pitfalls and fakes
These are the mistakes that cost collectors the most money with half dollars:
- Assuming every Kennedy half is silver — only 1964 (90%), 1965–1970 (40%) and special collector strikings contain silver.
- Spending 40% silver halves as face value; the dull edge without a copper stripe gives them away.
- Confusing the 1964 90% coin with the visually similar 1965–1970 40% pieces when buying in bulk.
- Polished or cleaned Walkers priced as mint state — original luster is the value driver.
