Strike
Broadstrike
The retaining collar failed, letting the metal spread outward during the strike.
How to spot it
The coin is wider and thinner than normal, fully centred, with no reeding on the edge.
Value impact
Modest premium; larger and more dramatic spread means more value.
Known examples
- Collarless quarters and dimes
