Jefferson 10 Piece Dining Set

I have purchased this 10 piece dining set - Table 5 chairs and 1 captains chair, China Cabinet, SIdeboard, as well as a dessert table.  Where the leaf fold out of it has the markings of Jefferson Woodworking Co. Louisville, Kentucky and it has the steel slider.  It also has the locking mechanism to release for the leaf to come out.  Looking to get an idea on its value.  I am located in Canada and I have been googling / researching as much as possible but I can not come up with much.  Any help greatly appreciated.

Thanks,

Fair
