Very Very Old Bookcase Please Help !!!!

Based on your images this is a "Married piece" meaning it's a marriage of bits of different pieces of furniture. It originally was the top half of another cabinet the carved piece at the top is not original to this piece either. Married or altered pieces like this tend to have very modest values when identified for what thye are, a piece like this often go at Auction for less than $100.00.

Can't really tell from the images, and it's made of bits from different ages.
