What is this and how much should I sell it for?

I just inherited this clock that says, "Colonial" on the face. I know absolutely nothing about clocks.

I can see that it has two big weights and a wind up key thing and a pendulum but that's all I know.

I don't think it has run for a decade so not sure of its condition.

I would like to sell it so would appreciate it if someone can tell me how I should describe this clock in a listing and how much is a reasonable price to ask for it.

Thanks for any help.
