antique field related people,antique dealers or anyone that knows something about antiques?

I recently had an inheritance from a far distance family whom were strangly enough not eligible according to will. The inheritance was reasonable but there was a particular object/set that was passed down from generations to generations. I was told bythe former employers that once served the previous recent relative who passed away that it all dated back to shang dynasty.

-I want to exhibit/put on auction the object. How do I do this?

-Also do i need to get it assessed first to know its worth?if so how do i do that?

-I heard theres 2 famous antique fairs in London that only comes yearly that exhibit/auction things that worththe same as the stuff you find in museums. any ideas about this?

-If the auction/exhibitions dont work how do museum works?can i sell it to the museum?

by the way i am from London and i dont know how antiques work and where to start.all your ideas and suggestions are most welcomed.

ps I havent got the object valued but lets just what if its not something ordinary that you just got out of your attic that i can go to any local dealers to value it. So any contacts/details would be great esp specializing in oriental objects.
