dining table and chairs, or individually

The chairs are in great condition, but the table is chipping away. If I could only get an idea how much the table would be if it was in good condition. I'm hoping to selling it for really cheap for someone to buy and fix up. It's a gorgeous table. I thought I saw the exact table on the Maine Museum wesbite when I googled "empire table (it dated 149 yrs ago).   It could be  a reproduction and made during a different era. This table is so rickety and it's odd, it has metal wheels at the bottom. I have no idea what kind of wood the chair and tables are. I bought the set at an outdoor market in Washington DC for $400 a couple years ago. I fell in love with the style of the chairs. If I can't sell the set, how much could I get for each chair? There are no signature or label anywhere on the table set.
