Need value of 3 inherited guns

I just recieved several guns from my Brother in law's estate. I am not sure of their value but all are in excellent shape and have been well kept. Here they are:

Remington Model 700 in 7 mm magnum with a 2-7x Redfield scope. This has a checkered stock. Wood is not fancy, no forearm tip. Ser# 39030

Beretta 390 Silver mallard 12 ga excellent shape w/ tubes

Beretta onyx 626 sxs 20 ga. 26" barrels looks like new w/choke tubes


I am trying to figure a price so I can put them up for sale. Thanks

hi,
remington 700 450 - 550
beretta 390 800 - 900
beretta 626.......?

you may have better luck with shotgunworld.com, i can't find info on a 626. the 625 i've found were going for 1200 - 1400.
