2011 D Lincoln Cent - Is This A Variety?

I recently purchased an endoscope to use for finding varieties. While looking for varieties, I came across the coin in the attach photos.

ON THE OBVERSE:

In the first photo, I noticed what appeared to be a "D" to the right of the mint mark. On closer examination, it looks like a 3 to me. I also noticed that, in the date, the "2" and the "0"are missing pieces at the top and bottom of both numbers, and the last "1" is cut-off at an angle, at the top of the "1".

In the second photo, I noticed that, commencing at the tragus of Lincoln's ear, extending up and to the right at roughly a 30 degree angle to horizontal, and ending about half way to the hair line, there is a tube with no detail in it. Also, the "R" in "TRUST" appears have a shortened leg on the "R". Finally, there is a line running parallel to rim commencing on both sides of the bottom of Lincoln's bust, and visible around 3/4 of the coin.

I did not notice anything unusual on the reverse.

Please tell me: Is this a variety, have I gone crazy with my new endoscope, or both?

Thank you.
