Remington's website gives suggested retail prices. They do not list the 11-87 as available in the Ducks Unlimited commemorative edition. They do have the D. U. Mod-1100. See the link below. Used weapon values depend on the condition and age.
The best shotgun shell for shooting ducks is a 3 to 3 1/2 inch 12 gauge with number 2 shot.

There were several different Browning models used as DU guns. Auto-5, A500, B-80, etc... Need to know exactly which model, and whether the supporting Ducks Unlimited paperwork is still with the gun, and so forth.
