The 1955 and 1943 are die deterioration doubling caused by worn dies. This is not considered an error. The 1964-D cent is damaged. It would not...

A rotating wire brush can leave this effect on copper cents. here is a previous thread https://www.cointalk.com/threads/damage.350754/#post-3903789

Looks like feeder finger damage as @alurid said Here is a recent thread. Compare the marks to your coin....
Although lamentations are associated with improper mixing, they can also occur due to gas bubbles and both are independent events. How many...
