I am a asking about a coin that I entered a question about that has not been approved to be answered two other questions I entered after the first one have been answered and here goes,the certification number on the coin is5976922-001 the coin is certified as obverse struck thru I found the coin in pocket change at Safeway I sent it in because it's bigger than an average penny I am not an expert but according to coin terminology I see no signs of the certification, would someone check the photos that NGC has I am planning to send it back for recertification it's an abnormal coin it has no marks showing it to be as it's certified as I stated I did send this question with a picture of the coin as my first question,the coin is thicker and wider than a regular coin.

Hello! If selecting Mint Error or VarietyPlus options on your submission form this indicates to our grading team to review the coin from all NGC Recognized Mint Error/VartietyPlus options. It looks like your coin qualified for the Obverse Struck Thru Mint Error designation. If there is a VarietyPlus attribute for this type of coin, then it would be listed on our VarietyPlus page. I have included a link to the page below.

I still don't understand, so if the coin is thicker and wider meaning also larger than a regular penny then would it be eligible to be a variety plus coin and if I resubmitted it would it be re-certified as an error and variety plus because it seems to be larger than a regular penny.
