It really depends on which exact model and when it was made, plus condition. Pics would help. I have three Colt SA revolvers, a Frontier Scout (early model, the two tone one), and two New Frontiers (one in 22 LR the other in 22 Mag). In average condition, it's probably a $300-350 revolver, Colt or not. There were some fairly rare commoratives tho', it's worth getting more details. - dan
