I posted a few of these coins before but never really got a straight answer if these are Damaged or they are Mint Error if Mint error then witch Error would it be under? And as for my 1964 someone commented they did something like my coin with their fingers, witch that seems hard for me to believe. Well anyways i hope this time i can get at less an idea of what error coins they mat be...
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 be possible for that to occur during the minting process.
All of them are normal for being in circulation. What you see was not something that happened at the Mint.
You can see the shiny spot on the S in Trust, and the mark on the cheek where whatever was used helped bend it.
You may wish to read this reference http://www.error-ref.com before posting error questions. It is a cornucopia of information.
