    It's called machine doubling. Your coins are not from a doubled die.

    Hardly anyone does :(

    It takes time to learn.
    First of all the correct Numismatic terminology is Doubled Die.. not double die. It's important to know that.

    Doubled Die is known as a Variety. It is explained how it occurs here - https://doubleddie.com/58222.html
    It is not a striking issue.

    Strike doubling such as MD - Mechanical or Machine doubling known as Worthless doubling is not a variety and explained here - https://doubleddie.com/144822.html

    DDD - Die Deterioration doubling is also Worthless doubling is not a variety and is explained here - https://doubleddie.com/144843.html

    It's a lot of reading. Good luck.
