Seriously though, those are scare guns in that caliber, although the 100 won't bring as much as a 88 would, my suggestion would be in the $500-600 range for the gun & although that is a nice scope they don't add much value on a used gun so I would add another $50-75 bucks for the scope
Hope this helps, maybe a PM to Doug or 88man would give a more accurate value.
