WTK: Value of Intrac MK-II NIG AK-74

What would an Intrac MK-II AK-74 new in grease, meaning the original plastic bag, in the original box, with original mag, certificate and instruction book, be worth?

The plastic bag with the weapon in it is not opened, nor has the selector been moved.

$650 at auction; $575 on consignment; $550 at a fun show in the Pacific Northwest.

HTH.
