I'm just new at buying antiques. I just bought this geisha brass sculpture it 17.5 inches in height and the width is 7.5 inches.  I was just wondering what is the value of it. what is the difference when the bottom is hollow or not?

These are oils on canvas, I can't read the artist' signature. I don't know if I should have them cleaned. I purchased them at an estate sale.

I'm struggling to find any information on this bell, like where it could be from or even when it is from. It is clearly handmade but there are no markings on it that I can see. I don't know enough about bells to even begin to know where to look. Thank you so much for your time.

Large antique farm table

Approx 7ft by 3ft. Beveled mirror. With wooden carved frame. Label on back says made in china, 2002. 

I can not find any markings on the chair but it has a similar look to a George Hunzinger platform rocking chair, even though this is obviously not a platform rocker.  I purchased whilst living in Ohio. Any help to identify or a possible value would be greatly appreciated. Thanking you kindly.
