Broadstrike Coin Value: Evaluating Collar Failure Errors
Broadstrike errors — coins struck without the retaining collar — carry premiums that vary significantly by denomination, the degree of expansion, and the coin's condition. Understanding these value factors helps you evaluate broadstrike finds accurately.
What This Means
Broadstrike values reflect the relative scarcity of collar failures on different denominations. Pennies are most commonly found as broadstrikes, while broadstrike quarters and half dollars are genuinely scarce. The degree of expansion and the coin's condition affect the premium within each denomination.
What to Look For
- Denomination — higher denominations are scarcer and more valuable as broadstrikes
- Degree of expansion — more dramatic spreading generally increases value
- Edge character — flat, smooth edge all the way around confirms broadstrike
- Full design — the complete design should be present, just expanded
- Surface condition — uncirculated examples carry significant premiums
- Centering — well-centered broadstrikes are more desirable than off-center broadstrikes
Common Mistakes to Avoid
- Confusing dryer damage with genuine broadstrikes — dryer coins show scratches
- Not measuring the expanded diameter to confirm broadstrike
- Assuming all broadstrikes are equally valuable regardless of denomination
- Not checking that the edge is smooth all the way around
- Overvaluing slightly expanded coins that may just be worn
What Affects Value
Broadstrike values scale with denomination: penny broadstrikes are most affordable, while quarter and half dollar broadstrikes command significantly higher premiums. Condition and the degree of expansion are secondary but important factors.

What denomination broadstrikes are most valuable?
Broadstrike values generally increase with denomination. Broadstrike quarters, half dollars, and dollar coins are scarcer and carry higher premiums than broadstrike pennies or nickels.
How do I measure a broadstrike?
Use calipers to measure the coin's diameter and compare it to the standard diameter for that denomination. The difference indicates how much the coin expanded without the collar.
Are slightly oversized coins broadstrikes?
Not necessarily. A genuine broadstrike shows clear, even expansion with a flat, smooth edge. Slightly oversized coins may be within normal tolerance or may be partial collar errors rather than true broadstrikes.
Should I get a broadstrike graded?
For broadstrikes on denominations other than pennies, professional grading is often worthwhile. Broadstrike pennies in circulated condition may not justify the grading fee unless the expansion is dramatic.
