I'm sorry for the delay, I missed your message.
Your Statue is a later copy of an old 'Head of Buddha' mainly found in southern Cambodia. Color and carving and also wear are not as what you would like to see in an original piece. Nevertheless it is a nice and well made copy. There is alway's demand for Buddhist objects so I think if your Buddha head came to auction it could make a price around the estimate I gave you.
