Please Help With S/42 Luger

I don't consider the $450 I paid for this one to be over priced at all!
You almost can not find any shooter for less than $500 and they will be badly buffed, reblued and/or mismatched. I got an all matching, very lightly buffed pistol with all markings clear.

A mis-matched S/42 ia only worth $500, but a reblued Luger with ground stock lug is worth $450? There has to be more than $50 difference somewhere.
