I've seen them sell for as high as $1175 NIB. Used should be in the $1000 range.
The value of a NWTF Remington 870 Express Magnum 12-gauge shotgun typically ranges from $300 to $600, depending on its condition, any modifications, and the current market demand. Special editions or those with unique features may fetch higher prices. It’s advisable to check recent sales or consult a firearm appraiser for a more accurate valuation.

New in the box, $500-600 (on a good day) Doesn't really demand much of a premium and if not new IN BOX, not any.
I think you are talking about a shotgun for the National Wildlife Turkey Foundation. With no other information I would be guessing 250-500.
I can not say of the value because mine is priceless, but performance is excellent I use mine to hunt deer mostly, and informal turkey shoots. Patterns great but tried many different choke/cartridge combinations to find what the gun likes best. Highly recommend this gun

Many companies have made firearms for the NWTF.
Without more specific information; 100-1000 USD
Most go for about 375-450 simply because you can get one from a store for 500. I would recommend asking 475 and accepting as low as 400 if offered.
