Northern Furniture Co., Buffet

I was given the buffet in 1982, but now my wife wants to sell it, and that's why I want to know how much it is worth and/ or how to sell it. It has a few minor scatches throughout. All of the doors and drawers work well. The top left drawer has a built in devider. I don't know what kind of wood it is made out of. The bottom of the drawers are dark brown (perhaps mohagany?).

Thanx
