$100-$200 if someone wants it, end user for a project
ie) Prince of Dubai for his real estate projects... highly unlikely but hey if they can pay $15M for license plates, to bad we couldn't get some of that oil money in the domain markets
If it was the other way round then big money. But I think as a developed domain you could earn some money from advertising, I don't you would get anything just for the name though.....
Having recently qualified in Prince I now own Prince4.com LOL
