Broadstrike Coin Errors
A broadstrike occurs when a coin is struck without the retaining collar that normally holds the coin blank in place and creates the reeded or smooth edge. The result is a coin that is wider than normal with the design spreading beyond the usual boundaries.

Full Broadstrike
The entire coin was struck outside the collar, creating a uniformly wider coin with the full design visible.
How to check: Measure the coin's diameter. It should be noticeably wider than normal with a smooth edge instead of reeded.
$25 - $300+Partial Broadstrike
Part of the coin was in the collar while part was not, creating an uneven expansion.
How to check: One side of the coin may appear wider than the other, with partial reeding on part of the edge.
$15 - $150Broadstrike with Partial Collar
The coin was partially restrained by the collar, creating a step or ledge on the edge.
How to check: Examine the edge for a visible step where the collar contact ended.
$10 - $100Quick Checks
- Measure the coin diameter — broadstrikes are wider than normal
- Check the edge — should be smooth (or partially smooth) instead of reeded
- The full design should still be present, just spread wider
- More valuable on higher denomination coins
- Confirm it is not post-mint damage (PMD) — broadstrikes have consistent striking quality
Frequently Asked Questions
How much is a broadstrike coin worth?
Values range from $10 for a common cent broadstrike to $300+ for larger denominations. The wider the spread and the scarcer the denomination, the higher the value.
How do broadstrikes happen?
The retaining collar fails to rise into position before the dies strike the planchet. Without the collar, the metal spreads outward beyond normal diameter.
How do I verify a broadstrike?
Genuine broadstrikes have consistent strike quality across the entire expanded surface. The edge is smooth or partially smooth. Upload to ErrorHunt AI for verification.
