Help! How do I identify the make/model of this?

I helped clean out a friend's house and this unopened rotor(?) was in the garage. I have been unsuccessful in identifying what make / model of vehicle it goes to. I'm not knowledgeable in auto parts. It's 11" in diameter. Does not have ventilation holes along the side. I thought selling it might be more valuable than scrapping it. Can anyone help?

Thanks!
