dale Earnhardt ceiling fan

Wanting to put in a ceiling fan in my shop, and an older gal that I know has a new in box dale Earnhardt ceiling fan. You know the harbor breeze brand that has the Earnhardt deco blades on it. She said she would like $150 for the thing, I want it for sure and I know it's a collectable item. But what do you guys think it's worth? I can't find any current comps online. I just don't want to pay twice what it's worth.
