Welcome to CT!!! This is actually common on Lincoln Cent Proofs of this era. It is not an error. More like a carbon spot on the coin. Yours is in a funny spot, but it adds no premium.
I agree, this is a carbon spot. It is considered unattractive, and will lower the grade. Unfortunately, this spot is right smack dab in the prime focal area, and its a big spot. The grade and value of this coin is going to be quite low.
