Rare brockage-counterbrockage combination error
- This 1965 Canadian nickel was struck into an underlying nickel that had a 50% partial brockage. The result is a counterbrockage of the Queen's bust next to a brockage of the beaver design. The partial brockage was from an off-center nickel, explaining why the Queen's head is cut off.
Keep in mind that the reverse die (bearing the beaver motif) is the hammer die while the obverse die (bearing the Queen's bust) is the anvil die.
This is one of the 8+ ways to get both a brockage and a counterbrockage on the same face.
