how much is a mossberg 12 gauge gold editon brand new never shot
It really would help if you put what model it is. As far as I know "Gold Edition" in and of itself is not a model.
Could it be a model 500 Gold Edition ? How do you know it is a Gold Edition, is that stamped on the receiver and or barrel?
In like new, never fired condition you are looking at a value of about $350-$450. Last MSRP was about $450 IIRC.
