Half Dollar Errors to Look For: Kennedy, Franklin & Walking Liberty

Half dollars are among the most interesting denominations for error collectors. Their larger size makes errors more visible and dramatic, and several half dollar series — Kennedy (1964-present), Franklin (1948-1963), and Walking Liberty (1916-1947) — have produced notable error varieties. Because half dollars circulate less frequently than smaller denominations, errors that make it into rolls and bags often survive in better condition.

What This Means

Half dollar errors cover manufacturing defects on all US half dollar types. The larger planchet size means striking errors like off-center strikes and broadstrikes are particularly impressive. Die errors including doubled dies, die cracks, and cuds are easier to see on the larger canvas. Pre-1965 half dollars are 90% silver, and 1965-1970 Kennedy halves are 40% silver, adding metal value to error premiums.

What to Look For

Doubled die lettering on "LIBERTY," "IN GOD WE TRUST," and "E PLURIBUS UNUM"
Off-center strikes — dramatic on the large half dollar planchet
Die cracks running through Kennedy's portrait or the heraldic eagle
Missing clad layer — exposed copper core visible on one side
Broadstrikes — oversized half dollars without edge reeding
Repunched mintmarks on pre-1965 issues with hand-punched mintmarks

Common Mistakes to Avoid

Not checking 40% silver Kennedy halves (1965-1970) for errors — these are often overlooked
Assuming all heavy half dollars are errors — pre-1965 silver coins are naturally heavier
Ignoring the reverse — significant errors appear on the eagle side
Not checking edge reeding — edge anomalies indicate collar-related errors
Cleaning silver half dollars before evaluation — this reduces both numismatic and error values

What Affects Value

Half dollar errors benefit from the denomination's larger size, which makes errors more visible and dramatic. Silver-composition half dollars with errors carry both error and bullion premiums. Kennedy half dollar errors are the most accessible to find because Kennedy halves are still produced and available in quantity from banks.

Frequently Asked Questions

Where can I find Kennedy half dollars to search?

Many banks will order half dollar rolls on request. Half dollars are produced in quantity but rarely circulate, so bank rolls are the primary source for error hunters.

Are silver half dollar errors more valuable?

Generally yes. Pre-1971 half dollars contain silver, which adds base metal value to the error premium. A doubled die on a 90% silver 1964 Kennedy half is worth more than the same error on a modern clad example.

What Kennedy half dollar errors are most sought after?

The 1964 accented hair variety, various doubled die varieties, and significant off-center strikes are among the most collected. Die cracks and cuds on early Kennedy dates also have followings.

Should I check Franklin and Walking Liberty halves?

Absolutely. These older series have their own error varieties, and examples found in the wild tend to be scarcer. Franklin half dollar bugs (die crack through the Liberty Bell) are popular finds.
