The form of the base is definitely savonarola. This kind of tilt top was popular in the latter half of the 19th century. As for value, you first have to remember that antique furniture is selling for a fraction of what it used to be worth. People want Ikea. As someone with a houseful of antiques it baffles me, but it is what it is. Value is also very dependent on where you live (I'm presuming that you'll sell this local pickup only). Where I live I can see this bringing $300-$400. It's a lovely piece.
