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.
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.
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.

Scan Your Coin NowBroadstrike values generally increase with denomination. Broadstrike quarters, half dollars, and dollar coins are scarcer and carry higher premiums than broadstrike pennies or nickels.
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.
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.
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.
