How much could this sell for?

I’m thinking about listing my old Cannondale kids quick 24. It’s a lightweight children’s hybrid bike for pavement and light off – road use. It has 24-inch wheel size, a rigid fork, flat handlebars, multiple gears, (7 speed setup), and obviously a bunch of other random stuff. It’s great bike for around 8-12 years old I’d say. It needs some cleaning up but how much do you all think I could list this for? or if it’s a bike I should just not sell.
