Would any of you have any idea what copy of 2112 is being shown here?

Don't use Discogs. but I have some experience with Rush vinyl as a collector although my goal isn't to have every variation of everything.
He's on the right track as far as I can tell. There are copies of Power Windows that are translucent and off that's 1985 (Which he claims that pressing of 2112 was made that year. Maybe there was a point in time that what Mercury was using at the time for whatever reason. Also possible that the album sleeve and record were put together at some point after it hit the wild.
I think the "70" on the label refers to where it was pressed. I'm sure there's a list of numbers somewhere that correspond to where the vinyl was made. I don't think the copy has any special value unless one is really into variations.
But most of this is guesswork. You might try the Hoffman Forum where there are people there who seem to specialize in variant pressings as a hobby.
I think I may have dumped my record club reissue of 2112 otherwise I'd have a look at it.
