2014 D Dime Error? If So, What Kind?

Hello, 1st off, I'm new to all of this so please pardon my ignorance on the subject. Myself and son recently became interested in error coins. I've encouraged it 100% as a hobby we can share. So far, we haven't found many significant errors. I came across this dime (by accident) and hoping someone can educate me on it! There's a cut going through the head that goes all the way across the dime. On one end, the edge flattens. There's also a similar cut through part of the center/back (but not nearly as obvious as the front). My pictures may not be the best, but I will gladly take more if needed.
