Your sale price will be what someone who wants it is willing to pay for it. It looks in very good shape except for the chip in the toe. I would guess between $500 and $600. I purchased the same gun in 1986 for $349.xx and I LOVE it!
Is it choked? What does it weigh? Those factors may make a little difference but I suspect in the classifieds here at $500 + shipping it wouldn’t last long. $600+ might take a little longer.
I've got a coach gun I bought not that long ago. Not even a scratch on it. Nice shotgun.
I think five to six would be right for that gun with a chip out of the stock. Someone that knows what they are doing could fill that right in.
