What is the value of the natural resources that are on halleys comet?

Answer 1

First, we have only limited information about the mass or composition of Halley's Comet, so we cannot give any even approximate value (on Earth) to the raw materials.

Second, like in real estate, location is everything; the ices and gasses may be relatively cheap of themselves, but they are already in space, and if we could capture it, it would save us the cost of lifting it out of Earth's gravity well.

Finally, a painting is a couple of bucks worth of cloth and paint; the value comes from the beauty of the thing. Ditto Halley's Comet; even if it were possible to capture the comet and convert it into an atmosphere for a space habitat, the sentimental value alone would make it impossible to do. Comets are plentiful; we can leave this one alone, like a historic building.
