depends on condition, but a nice used one can be picked up for around $450.00. I have seen new ones for $700 to $900, and people trying to sell them used for as much as $850, but you can get a used one from a person (non-dealer)
for about $450 to $500.
50-2000 USD depending on specifics.

You didn't describe anything about the condition it is in. Does it have the box, papers or any accessories? What finish? How much of the finish is left? Any surface rust, wear, or blemishes? What type of material are the grips made out of? Does it come with a factory letter from Colt? Any engraving? They all affect the value. Without more information the best I can do is give you a price range of 500-2000 for a Colt Mark IV Series 70 in 9mm Luger.
