How to determine grade of Browning BAR Mark II

I have a Browning BAR Mark II in 7MM Rem Mag and am having trouble determining what grade it is. On sites like gunbroker.com i have seen others list similar items as Safari Grade, Grade II, III, IV, V, High Grade, etc...Mine was manufactured in 2001 and has the hard alloy receiver with the game scene engraving (pair of moose on one side and pair of elk on the other) gold trigger, etc...any help would certainly be appreciated. Thank you.
