3pc Gordon's Fine Furniture tables  

We have our grandmothers tables, they are a set of three, they are very shinny black around the edges and fade into a grey/green. they are beautiful and look kind of retro style. 1 is a kidney shaped, 1 is an end table and 1 is a square corner table with a raised shelf in the corner. The metal tag on the bottom of each table says "Fine Furniture, Gordon's Inc. Johnsonville, TN. We were wondering what the value of these tables are? Can you help us? Two are in great shape and the smaller end table has a few blemishes. not too bad though.
Thanks for any info you might have
