40% Silver Kennedy Half Value: 1965-1970
The 40% half dollar is a clad silver coin with a different weight and metal content from the 1964 half. The statute specifies silver in grams for the whole coin; the silver proportion of the outer layer alone is not the whole-coin fineness.

Price may be out of date. The saved quote is older than 36 hours or flagged stale. Check the source before relying on a metal estimate.
Melt value is an estimate of the silver content only, at the dated spot price shown. It is not an offer to buy or sell, and not investment advice. Dealer offers are often below melt, and collectible coins can be worth more.
Silver content and the formula
Nominal total weight: 11.50 g. Composition: 40% silver overall, clad construction. Silver content: 4.6 g, approximately 0.14789 troy ounces per coin.
Specification verified against the primary source below. Ounce values are rounded for display; calculations use silver grams divided by 31.1034768.
Melt value (USD) = (4.6 g ÷ 31.1034768 g/ozt) × silver spot (USD/ozt).
Source: Coinage Act of 1965, section 101(a)(1), 79 Stat. 254. Nominal original weights are used; wear and loss of metal can lower actual silver content. A troy ounce is different from the ordinary household ounce.
What can make one worth more?
The 1971 report separates Denver uncirculated-set production from San Francisco proof coins for 1970. Keep that issue distinction when researching collector demand. Neither production count establishes the value of an individual example.
Date, mint mark and condition
A report footnote says the Denver coins were produced for uncirculated sets with an overrun for replacements. Do not describe all of them as ordinary change released into circulation.
Keep the date, mint and any suspected variety together in your notes. A mint mark identifies a production location; it is not a grade. Preserve the surfaces rather than cleaning a coin to make it look brighter. If an unusual coin warrants professional assessment, have it graded by PCGS or NGC; neither service sponsors this guide.
Suspected errors need authentication
Doubled-looking letters, a weak design or unusual color can have more than one explanation. This guide does not identify an error variety from a description or assign a premium. A damaged or altered coin is not automatically a mint error. Obtain an independent assessment before attaching a variety name or collectible value.
Mint-report production records
These are the manufacturing counts and categories stated in the linked Mint publications, not a survival census or a grade-price table. They can include proofs, assay pieces and production outside the year on the coin. They should not be substituted silently for circulation-strike catalog mintages.
