I'd need to see a photo of the whole coin (please always post whole coin obverse and reverse shots with every post you make asking questions), but it looks like a struck through grease coin. No real premium to this, but some of the more dramatic ones are fun to find.
Hi Imho, it appears to be a struck through grease cent. And like Seattlite86 said it’s best to take a picture of both sides. Thank you. http://www.error-ref.com/struck-through-smooth-viscous-material-grease-oil/
Not a weak strike.. that is a different issue. Just a simple Worn Die Strike. Struck through grease is correct.
I stand corrected. The strike is weak, because of being struck through grease, but I think I get the distinction you're making, since it's more than just a regular weak strike from normal causes.
