I don't think I have EVER seen a green skill-level packaged Nighthawk on ebay, but have seen the Gemini Titan.
Both were in that packaging only in 1973 I believe.
In 1974 they were gone.
The non skill-level packaging is far more common.
I think there were two Nighthawks on ebay recently.

There are VERY FEW kits I would trade my Nighthawk for.
A boxed, sealed Enerjet Athena is one.

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, and HAVOC !
