I have an Item that weighs about 25 pounds and is solid wood and is round and about an inch thick.  Its is approximately 2 and a half feet in diameter.  I could not find any dates or names.  On one side of the item is plain wood and the other is an egyptain style picture created with inlays of different items, for example brass, or shell and other metals.  I just need to know what it is and if it is worth anything.  Your help is appreciated.

Thank You,
