I know that each of you must have at least one die clash in your collections. Let's see them. I'll start.

A die clash on a coin is a mint error that occurs when the top (obverse) and bottom (reverse) dies collide without a blank metal disc (planchet) between them. This extreme pressure imprints parts of the design from each die onto the other, leaving mirrored ghost images of the designs on future coins.

How it Happens:

The Process: A coin is stamped by two hardened metal dies. Usually, if a blank coin fails to feed into the press, a built-in safety mechanism stops the dies from touching.

The Collision: If the machinery falls out of adjustment, the minimum clearance drops to zero. When the hammer and anvil dies smack into each other, they press their designs into the opposing die's metal.

The Result: When blank planchets are finally fed back into the machine, the damaged dies will stamp coins that show faint, sunken (incuse) outlines of the opposite face's design.

    Clashes on both sides—obverse shows some of both wings, reverse has almost full pigtail, the chin line on the left wing, the clash at the beak is weak, the ends of the arrows.

    On this example, note the buckled reverse die to the right of S (CENTS). This die was replaced by a different die that does not show this buckling. So the obverse is paired with two different reverses.
