Found in change this 1979 d penny, there is a strike on mouth but not sure if it's a pmd, it looks like its smoking, also the mint mark looks filled?,   on reverse of coin there are also strikes, but not sure if its damage or error,

Your coin is definitely damaged, no doubt about it.  And the mint mark is normal.  The D mint marks on many cents minted at Denver from the 1970s have that style of mint mark that looks filled.  You just have a regular damaged 1979-D cent with no additional value.

Tom's right. It's been trashed, probably in the Wiggly Piggly parking lot or someplace. The mint did not do that.
