I know nothing about Norco but this appears to be a basic, low end bike. My guess would be 1980s.
No real value to a vintage enthusiast but certainly nice enough for someone to use for simple riding. Assuming tires are decent and everything works, I’ll put it as low as $50 and as high as $100.
If you plan to sell, lowering the stem and raising the saddle a bit should help curb appeal. Small bike probably suited for someone on the shorter side of 5 ft.
