Firstly the comparable prices are avialable on internet, should be looked to Ebay,
-the 44 sgx with riveted grips are going about 100/150USD higher as normal price for matching, it depends on real pieces condition and value of seller
-the grey ghost also 44asw ff and gg range would go mutch more above 400USD, teoretically by low price, You could remove blueing on the piece and restore on the piece the phosphating, by price under 100 it would be real even missmatch
-The other makers 44 dated production as obviously mint and matching should be higher priced as well used prewar pieces of 1937/39 period or early war S84/98 bayonets .
I personally wouldnt buy a missmatched pieces of late war,
-same as heavy used pieces or with patina pieces are always better for collection as wrong way cleaned missmatches
