I was told at the ft worth gun show just two weeks ago that the 12 ga is not worth any thing like your 20 ga . For some reason the 20 ga is worth approx.as much as a $1000.00 dollars more If I were betting I would say around 900.00 for the 12 ga.maybe more.Take it to the gun show next week.Some one up there will surely know Take care Bill H
