Hello @Dascher,
Thank you for reaching out to us and for sharing the beautiful close- up photos of you coin. A variety is a coin that differs from its basic design type in some distinctive way and is thus differentiated by collectors, while a mint error is the result of human or mechanical error during manufacturing. NGC may recognize a double die as a variety but does not recognize machine doubling as a variety.
I would not be able to offer an evaluation via photos and the coins would need to be examined by our expert graders to determine whether the doubling qualifies for a variety as a double die. To choose this service, you will choose the VarietyPlus service on the submission form not Mint Error. If you feel it is more likely that the coin is doubled due to a striking error, this will fall under Mint Error service. Regarding mint errors, it is also important to note that very common errors or errors that are within mint tolerances do not receive mint error designations. Since the doubling is fairly minor, it may not qualify for designation as a strike error.
Keep in mind, when submitted for VarietyPlus and/or Mint Error service that fees do apply regardless of the final designation.
