How much can i sell it? Cause i need money right now, and i have nikkor lense 70-3000 mm

Nowhere near what you want - particularly if the lens has no motor.

It's only worth what someone will pay.

Since I'm always in the hunt for old cameras, I wish you'd price it lower than $250.

They seem to selling from $250 to $300, with the standard 18-55mm lens. You should be able to get about that much, if it is in perfect working order and very little damage, such as scratches.

£150 for the body and £75 for the lens.
