My father-in-law passed away recently and left me two NIB Colt 1911 pistols. One of the guns is blued and says Colt Series 70 Government model. It came in a woodtone box and sat in styrofoam. It has wood grips and the finish is blued. What is it's value? Also the other pistol came in a blue plastic box. It is a Gold Cup Trophy. It is made of SS and isn't very old according to the test target in the box (1997 I think). What is the value on this? What is the difference between a Gold Cup National Match vs. a Gold Cup Trophy?
