Well... After I got my SQ Jazz (for cheap) I looked at a lot of MIJ Squier basses. A lot. No lie, hundreds of hours. Found out enough to also get an SQ P bass (for cheap.)
About the lowest I have seen for an E series J bass is ~$150, about the highest was
~$500 or so. Your range of $2-400 seems about right.
The second pic, the smaller mark, seems pretty typical, I've seen many of those. The larger mark also looks typical, but may indicate a heavy impact/blow has struck the body at that point. Probably nothing to worry about, just sayin'. It is an F-type intstrument.
The pic makes it look like it's basswood under the paint, which would also be typical for that era/build type. Nothing wrong with that, just sayin'. Might bother some.
Unplayed, I'd go 2 bills or so. If you play it, and like it, pay as much as it's worth to you.
