Same thought^^^^^^ what he said. That's the actual value depending on condition (your pic isn't exactly appraiser quality).
It's a fine buy at $115, if that's what it's WORTH TO YOU, to get your son into shotgunning.
Real value is what someone's willing to pay. I would offer $80 and see where it goes from there.
I know they are getting high and hard to findI think you did well on price. I just last month sold the .410 my dad gave me when I was 10. It was a New England Arms single shot. I listed it for $150 and sold it for $125. You can't really buy a good new one for that price anymore.
The only reason a 410 should have that big of a spread is a open choke if it has a full choke it should have a nice fairly tight even pattern.....The first shotgun I ever had was an old Mossberg bolt action in .410 that I was given to me by my Dad when we lived on the farm in Michigan when I was a kid. My Dad sawed the stock off to fit me and attached a fabricated plexiglas butt plate. I did kill a few squirrels with it and my Dad claimed I was the one who killed a pheasant that we both shot at, but I am not so sure that he actually killed it and gave me the credit.
But now I wonder if a .410 is a good idea as a kid's starter shotgun. It is difficult to hit with, not because of the size of the pattern (the pattern is as wide as a 12 gauge), but the pattern is so sparse with big gapping holes that hitting a game bird or animal with enough pellets to make a clean kill is difficult even for an experienced shot, much less a child. Better to give the kid a 20 gauge with light loads or better yet, a 28 gauge if one can be found reasonably.
