I generally see ones like that in 500 range
That is about right. Max would be about $600. Naturally Boomer will pay more for 1950s five screw flat latch with original box. Less common variations like 3" with banana grips will obviously bring nice premium. The gold standard in this category is Performance Center
Pro Series Magnum J-frame without lock. Used samples in excellent condition can be found in $550-$600 range, that is where the game is at.
