1927 Half Dollar Error List with Pictures
A regular 1927-S half dollar graded MS62 sold for $1,920 at Heritage in January 2025. That price reflects an unworn coin, not a confirmed weak-strike error.
The 1927 half dollar errors and strike features below span an estimated $100–$2,000. Some add an extra line or remove metal; others leave the design faint from the start.
Read on to learn what separates these features from wear and damage.
1. 1927-S Walking Liberty Half Dollar Die Crack Error (Estimated Up to $400)
A thin raised line running from the border into the design can reveal a cracked die. A die is the steel tool that stamps the coin.
Silver can squeeze into a crack in that tool during striking. The coin then carries a tiny raised ridge where the tool had a gap.
Cracks of this kind are reported for 1927-S, but no exact path is identified. Follow the actual line on your coin.
A scratch usually cuts into the silver. A broad raised lump at the rim needs a different explanation from a narrow crack.
Estimated Value
A circulated 1927-S with a small raised crack has an estimated value of $100–$400. The year guide places ordinary, moderately to lightly worn coins in the low hundreds.
Most of this range therefore comes from the coin itself. A clear crack may interest an error collector, but a faint line need not add much.
Cleaning, heavy wear, and damaged surfaces can matter more than the crack’s length.
How to Identify
Look for the 1927 date and the S near the lower left of the back. Then use a 10× magnifier to follow the line from the border into the design.
Change the light angle. A raised ridge should remain visible from more than one direction; bright scratch edges can be misleading.
Check the coin with a scale and calipers against the original 12.50 grams and roughly 30.6 millimeters across. Inspect the grooves around the edge for nearby impact damage.
Do not scrape the line to test it. For a quick distinction from a scratch, follow its full path and check that the line rises above the surface.
2. 1927-S Walking Liberty Half Dollar Lamination Error (Estimated Up to $500)
A thin layer of silver may lift like a flake or leave a shallow rough patch behind. This type of metal separation is called lamination.
It can begin with a weakness inside the metal strip used to make the coin discs. Striking does not always seal that weak layer.
Lamination is reported for 1927-S, without a confirmed position on Liberty or the eagle. The edge of the peeling area is more useful than its location.
Look for a natural layer. Corrosion pits or a scraped surface can remove metal without producing the same kind of separation.
Estimated Value
Circulated 1927-S halves with visible lamination have an estimated value of $150–$500. A 1912-S Barber half with an attached peeling layer sold for $89 at Heritage in March 2026.
That comparison was graded PCGS VG8, a heavily worn grade. It shows a different date and design with the same kind of metal flaw.
The 1927-S can have a higher basic value, while a large flake may attract some collectors and discourage others.
How to Identify
Leave an attached flake alone. Lifting it can break it off and destroy the feature you want to examine.
View the damaged area from the side under a lamp, then inspect it with a 10× magnifier. A shallow layer should meet the solid surface naturally.
Compare the coin’s weight with the original 12.50 grams using a scale. A very thin flake may make little difference; calipers should still show about 30.6 millimeters across.
Check both sides and the edge grooves for scraping or chemical damage. For the quickest useful check, look along the patch’s boundary for a thin peeling layer rather than separate pits or tool tracks.
3. 1927-S Walking Liberty Half Dollar Curved and Straight Clipped Planchet Errors (Estimated Up to $1,000)
A curved bite or a straight missing edge can start before the design is struck. The coin begins as a blank, a round disc cut from metal strip.
A cutting punch that overlaps an earlier hole can leave a curved gap in the next disc. A punch near the strip’s end can produce a straight missing edge.
Both forms are reported for 1927-S. No specific size or position is established for these reports.
The shape alone is not proof. Someone can cut a finished coin, so the edge and nearby design need close inspection.
Estimated Value
A circulated 1927-S with a genuine clip has an estimated value of $200–$1,000. Larger, clearly formed clips may reach the upper end.
A 1942 half with a one-percent clip brought $126 at Heritage in September 2019. It was graded PCGS AU58, showing very little wear.
That tiny clip is a different-year comparison. The 1927-S date and the amount of missing metal both affect the estimate; a straight edge alone does not guarantee extra value.
How to Identify
Weigh the coin first. A noticeable missing piece should reduce the weight below the original 12.50 grams, though that alone cannot rule out later cutting.
With calipers, compare the remaining round portion with the normal 30.6-millimeter diameter. Then use a 10× magnifier to inspect the missing edge and nearby design.
Saw marks, filing, or abruptly cut edge grooves suggest damage after minting. A real clip may also leave a weak rim directly opposite the missing piece.
That weak rim is helpful when visible, but it is not equally clear on every coin. For a quick check, inspect the missing boundary for natural striking and compare the opposite rim for weakness.
4. 1927-S Walking Liberty Half Dollar Weak Strike Feature (Estimated Up to $2,000)
Liberty’s fingers can look faint even when a coin has never circulated. The metal did not fully fill the deepest parts of the stamping tools.
This is called a weak strike. On 1927-S, useful places to compare include the hand, gown folds, and feathers on the eagle’s breast.
Look at those areas together. A single smooth patch can also come from later wear.
Weak striking is mainly a quality issue, not an error that automatically adds value. Original shine can survive across soft details, while wear tends to rub that shine away from exposed parts.
Estimated Value
A softly struck coin around MS62 has an estimated value of $1,500–$2,000. MS62 describes an unworn coin that can still show noticeable marks.
A regular PCGS MS62 example sold for $1,920 at Heritage in January 2025. It was not sold as a weak-strike error.
The estimate allows for soft detail at a similar level of preservation. Collectors may pay more for a sharply struck coin, rather than reward the weak detail.
How to Identify
Choose a sharp 1927-S of similar condition for comparison. A heavily worn coin cannot show how much detail an unworn example should have.
Tilt your coin under one light and use a 10× magnifier to study the hand, gown, and eagle’s breast. Look for original shine running through faint details.
Rubbed areas often lose that shine. Check the edge grooves for smoothing, and confirm the S on the back.
For an unworn example, a scale should read near 12.50 grams and calipers about 30.6 millimeters. To separate weak striking from wear quickly, tilt the soft area and check whether its original shine continues across it.
Conclusion
Estimated values run from $100 for a circulated coin with a modest crack to $2,000 for an unworn example with soft detail. Those figures describe different conditions, not a guaranteed reward for every unusual mark.
Look for raised crack lines, peeling metal, or naturally formed missing edges. For weak strikes, study the original shine.
The $1,920 regular-coin sale does not establish an extra error premium.
