As the fellows said, it all depends. I have one here that most likely is not worth even that $100 guess. One in superb condition, with a good bore, likely will go 2 grand or better. I saw a nice one about 8 years ago, went for $1600 then, would doubtless go for much more now. It was rather cherry, though.
If you can provide us some good photographs, right and left side, close-ups of the receiver markings and the action, butt markings, somebody will be able to make a ball-park evaluation.
After that, it's between the buyer and the seller..... and generally they tell no tales.
Hope this helps.
BTW, I note the very low post count. Welcome aboard!
