Well, at the risk of being harpooned (again) I would offer the opinion that if in absolutely pristine condition it would be of some interest to a collector and price would be whatever someone was willing to pay to have it in their collection. If it is worn and reduced to "shooter" grade, then nearly $500 sounds very high to me. I bought one of these (pre-M20 made in 1955-56) at a gun show in Denver two years ago from an FFL for $199. It is in about 70% condition and shoots just fine. I like old guns with character (honest wear) and I would rather have one at 70% for under $200 than a perfect specimen at $500. But that's me. What do you want the gun for and how badly do you want it?
