SILVER COIN FIELD GUIDE

Which Kennedy half dollars are silver?

Start with the date. Then check the issue before combining coins in a silver calculation.

The short answer

Kennedy halves dated 1964 contain 90% silver; the regular 1965–1970 issues contain 40%. Ordinary circulation issues from 1971 onward are copper-nickel clad, but later collector editions include silver. This page’s calculator profile covers 1965–1970 halves only.

Dates and composition at a glance

Identify the issue before choosing a calculator profile.
Issue	Composition	Check before calculating
1964	90%	Use the 1964 profile.
1965–1970 regular, SMS and proof issues	40%	No proofs dated 1965–1967; those collector sets are SMS. 1970-D is Mint Set-only.
1776–1976-S silver collector issue	40%	Proof and uncirculated silver editions exist; clad Bicentennial coins also exist.
1992–2018 silver proof Kennedy	90%	Identify the silver issue; do not assume every S proof is silver.
Silver proof Kennedy issues from 2019	99.9%	The silver-proof standard changed in 2019; identify the actual product.
2014 four-coin anniversary silver collection	90%	Four different finishes; not limited to ordinary proof.
1964–2014 anniversary gold proof	Not a silver issue	3/4 troy ounce of .9999 fine gold.

Sort the dates before counting the silver

Separate 1964 halves from 1965–1970 halves. They share the Kennedy portrait but have different metal content. Keep later dates, proofs and packaged collector issues in a separate group until their exact issue is established.

For matching 1965–1970 halves, the published silver content is 0.1479 troy ounce per coin. Multiply that by the quantity and a current silver quote for a contained-metal estimate. Collector condition and attributed varieties need their own comparison.

Silver exceptions after 1970

The 1776–1976 date does not establish silver. Bicentennial halves were made in copper-nickel clad and as 40% silver S-mint collector issues. Identify the exact coin or set before choosing a profile.

Silver Kennedy proofs returned in 1992: the 1992–2018 silver-proof issues use 90% silver, while the silver-proof standard changed to .999 fine silver in 2019. Clad proofs also exist, so an S mintmark or mirrored finish alone is insufficient.

The four-piece 2014 anniversary silver collection contains 90% silver coins in proof, reverse-proof, enhanced-uncirculated and uncirculated finishes. The separate 1964–2014 gold proof is .9999 fine gold; it does not belong in a silver calculation.

Set aside a 1970-D for a closer comparison

The 1970-D was distributed in Mint Sets rather than released for ordinary circulation. Record the mintmark and condition before treating it like an interchangeable silver half. The 1970-S is a separate proof issue.

Special Mint Set coins from 1965–1967 are not proofs. Establish the finish before applying an SMS variety name; the date by itself is not an attribution.

OPTIONAL · ONE-MINUTE CHECK

Put that idea to work.

A 1964 half and a 1967 half look similar. Should you count both under the 40% profile?

No score, no penalty. Use the explanation and try again.

Questions collectors ask

Is a 1967 Kennedy half dollar silver?

Yes. The regular 1967 Kennedy half dollar and its Special Mint Set counterpart contain 40% silver. Use the 1965–1970 profile, then check condition and any properly attributed SMS variety separately.

Are all 1776–1976 Kennedy half dollars silver?

No. Copper-nickel clad Bicentennial halves and 40% silver S-mint collector editions both exist. The dual date alone is not enough; confirm the issue before calculating.

Why should I check a 1970-D separately?

It was sold in 1970 Mint Sets rather than released for ordinary circulation. It still contains 40% silver, but its condition and collector interest deserve a separate comparison before sale.

Similar portraits can hide different metal totals

Sort mixed Kennedy halves before choosing a quantity. Combining 1964, 1965–1970, and ordinary later clad coins under this one profile would give the wrong metal estimate.

For a 1966 SMS No FG attribution, Special Mint Set status and completely absent initials both matter. Faint initials are not the same as missing initials.

Where to look. Match the date first: 1964 is 90% silver, while this 1965–1970 group is 40%. Special Mint Set status must be established before applying an SMS variety.

Dates and details worth a second look

This is a selected watch list, not every key date or variety in the series. Finding a matching date is a reason to inspect further—not proof of authenticity, grade, or a particular value.

What do these collector labels mean?

Better date. A date or issue that merits its own comparison, not an automatic high-value finding.

Variety. A specific attributed design or die difference, not every coin with that year.

Two questions, not one price

What is the contained metal worth? This profile uses 0.1479 fine troy ounces of silver per coin. Multiply that by the number of matching coins and a current per-troy-ounce silver quote. The calculator shows the quote and its freshness when available.

What might a collector pay for this coin? That takes the exact issue, condition, surfaces, finish, and any authenticated variety. The checkpoints above explain why a collector sale may differ from the metal estimate. A calculated melt value is neither a guaranteed buying offer nor a complete appraisal.

The listed weights are standard reference specifications, with rounded published fine-metal values. They do not measure wear, damage, missing metal, or authenticity in your individual coin. Gross grams include the alloy; fine troy ounces describe the precious metal itself.

Build a useful comparison

Record the full date, mintmark, denomination, and finish. Photograph both sides and any diagnostic detail.
Use the specific references above to check a suspected variety. Do not clean the coin to make a feature easier to see.
Compare completed sales for the same issue and similar condition. Separate proof, special-strike, and attributed examples from ordinary coins.
Record shipping and other costs separately. An asking price or one exceptional auction result is not a typical sold price.
