Agree with Joshua. Below is an example and below that shows how the reverse imprint would look on the obverse, shows where to look on your cent for other markers. It is actually easier to see these from a normal photo, but taken from different angles you can see different details.
What @SensibleSal66 is showing is mechanical doubling, but that is not what your error is here. It is worth something, but not really very much. I see examples like yours showing minor clashing selling for between $1 - $5. In my opinion, it is worth holding onto and starting your own error collection, but not selling.
It's also been called the Lincoln Prisoner Cent Neat. But it's worth 1 Cent. It's stated on the reverse Oh, maybe you mean if the issue has a premium? It's whatever a collector of die clashes is willing to pay for it. But no high premium really.
