Antique Table and Chairs Cain Seats and Clawed Feet Table

I was with my dad when he bought these antiques in 1975.  I have no idea how old they really are. I see some similar that says 18th Century and some 1960 so no clue. Any help you can lend to know value would be great. I see 1K to 7K. Huge range.
