1891 Half Dollar Error List with Pictures
An 1891 half dollar sold for $48,875 in November 2010. Its exceptional condition drove that price; a faint extra line beside the eagle does not create the same value.
For 1891 half dollar errors, look closely at the open areas around the eagle. Some hold traces left by clashing dies.
The well-preserved, mirrorlike coins discussed below have an estimated range of $2,000–$3,000. Keep reading to learn what those faint shapes can reveal.
1891 Liberty Seated Half Dollar Die Clash Error (Estimated Up to $3,000)
A faint extra shape beside the eagle may come from the front design. The two dies, the steel tools that stamp the coin, sometimes hit each other without a blank between them.
That collision can mark their surfaces. Later coins then pick up faint traces of the opposite design.
Collectors call this a die clash; the affected coin does not need to be struck twice. A series reference describes frequent reverse clash marks on regular 1891 coins.
Search the open spaces around the eagle. Different coins may show different traces, so no single stray line identifies every example.
Estimated Value
Estimate $2,000–$3,000 for mirrorlike regular coins graded MS63–MS64, meaning preserved coins without circulation wear. Recorded sales include $2,400 for an NGC MS63 PL CAC in March 2024 and $2,880 for an MS64 PL in December 2025.
These prices value complete coins, not a separate clash premium. The $48,875 MS67 record belongs to a much higher level of preservation.
A faint clash alone does not justify that higher price.
How to Identify
Start in the open spaces around the eagle. Use a 10× magnifier and move the lamp until faint shapes stand apart from reflections.
Compare each shape with the front design. A true clash should fit a part of that design when the two faces are correctly lined up.
Fine parallel lines may come from polishing the die, while random cuts can come from later handling. One vague squiggle is not enough.
Check that this Philadelphia coin has no mintmark. A scale and calipers should show about 12.50 g and 30.6 mm on an unworn example.
Inspect the grooves around the edge, known as reeding. A reverse outline that clearly matches the opposite design gives the quickest useful clash identification.
Conclusion
Faint shapes around the eagle can tell you that the dies touched before the coin was made. The shape must match part of the opposite design, rather than simply look unusual.
The estimated $2,000–$3,000 range values the well-preserved mirrorlike coins discussed here. The $48,875 record belongs to an exceptional MS67 coin, and neither amount should be treated as a guaranteed premium for a small clash mark.
