Die clash - Errors and varieties
A die clash occurs when the press needs to strike the blanks quickly. Sometimes and for various reasons, a blank fails to be sent to the press. When this happens, during the striking, the two dies come into contact with each other. The result of this contact is an exchange of the highest points of design from one die to the other. When the next blanks are struck with these damaged dies, the design reproduced on the opposite die will be visible on the coins.
Multiple die clash
Occurs when the same pair of dies collide several times, including a slight movement of the hammer between each collision. Can also occur when there is vibration during the collision, leaving several marks close together.
Example : 5 cents 1872 H
Rotated die clash
Occurs when a die is not well aligned with the other one and there is contact between the two them.
An die clash with a single clash mark on one side lower than 25 % of the diameter is considered minor, while a die clash visible on both sides of a coin, a multiple die clash, or a die clash visible on at least 25% of the diameter is considered major.
