Help with Identifying dining table and value

Hello! I recently inherited this dining table and am wondering what era and style it is along with type of wood and what it's value might be. I'm looking to sell it in the Seattle area and I don't know what to ask for it. It expands but I could not open it by myself so the dimensions are only for it closed. It's 42" x 42" and 29" tall. Appreciate any help! Thanks!

 

Very unusual support and leg configuration (at least I haven't seen another. )

The two carved panels underneath remind me of the style often called Empire, but wait for others to confirm. How many leaves does it take?

Again - this looks like oak. I think this should go well in this neck of the woods.

 

2 leaves I believe.

 

Circa 1890 5 leg Eastlake style oak table. Maybe a few hundred dollars on a very good day in my neck of the woods. On a bad day, less than $100.00.
