Protecting Dad's estate

I'm trying to find the values of of Three guns My Father left in his estate.Any help would be greatly appreciated.They are:1. a Browning model 12,20 ga,pump shotgun with 25" barrel,ventilated rib sight and checkered,satin- or oil-finish stock & pump handle.The only scratches or wear I can find are on the ejector cover and bump that stops forward pump movement.2.A Browning.22 cal. semi-auto rifle that twists to break down,& loads through the side of the stock.18" barrel.It is also checkered, but has high gloss finish.It has a Simmons 3-9 X 32 scope installed.Last is a Smith&Wesson, nickel plated,.357 magnum revolver with custom wood grips that have an elk's head deeply inlaid and/or engraved on the right side.1 7/8" barrel.Anyway, any help with either the original retail or today's used prices on these would be a great help to me, as I'm not the 'gun guy' Dad was.Thanks for checking this out!

your model 12 browning is valued at 425 good -825 nib, your 22 semi auto has 3 grades and all revolve around how fancy it is ,made from 1956-1974,,book value is 400 vg-650 nib for a grade 1 not real fancy model(no fancy game scenes),,finnaly your colt may be a couple different models but i'll take a guess that its a dectective special and the book values them in the 300-500nib depending on which version it is,,thats as close as i can get on the colt without knowing the exact model,,
