What is the value of a bps 12 ga 3inch chamber special steel game gun model 20.5 engraved deer and turkey scene?

I don't know the current value but I payed $600.00 for it new back in 1993. It is a very accurate slug gun with it's 3" external rifled choke. It was a very limited produced gun so I think it's value has to be high now. It's a great looking gun and with the adjustable rear sight is almost as accurate as a rifle at 100 yards. This is my favorite shot gun for hunting because it is light and the short barrel makes for easy mobility. My A5 mostly just stays in my gun case unless I go to the range just to have fun.
