China Hutch

I have an Antique China Cabinet that belonged to my great Grandma. I think it is Black walnut and has some kind of madellion on the very top.  As you can see by the photo it has a claw foot  that has popped off.  The reason I SAY POPPED OFF IS because it looks like the glue came off not broken.  I have the complete piece.  It also has glass that has a clean crack on one of the back shelves which u cannot see unless you know where it is.  Everything is original nothing replaced or done to it even the key is original.  Glass is very very thick.  Can you tell me the origin and name of hutch and how much it is worth?
