White Furniture Company Dining Set

I have a set that was handed down to me. I am trying to find the value for the items to consider selling or passing to a relative.

There is an oval dining table with six chairs and two leaves. I also have the felt topper that fits exactly on top to hold a table cloth in place. Lot 813; 590-I Table

There is a buffet with it as well. Lot 31; 590-7 Buffet

There is also a tea cart that does not roll. Has two flaps on the end that raise up for more length. Lot 157; 590-19 Server

Any help would be appreciated.
