Die gouges?
Knowing that it's incuse makes me agree that it's an error.
In 1970, mint marks were punched into the individual dies by hand. Their placement will vary from die to die. The depth of the punch will vary...

The first pics make it look like the blob is raised, while the later pic makes it look like another coin might have been pushed into it....

I see nothing unusual.
What makes you think it's an error? The circle? That's damage cause by a counting or rolling machine.
It's worth face value. Don't spend it all in one place.
