Hi! We have this set of tables that we've been told are 60' mod. Can anyone please confirm as well as an added bonus of knowing the designer?

I did some googling and found a website with very, very similar side tables selling for $2400 for the pair. We have the coffee table as well so I'm wondering what our value could be.

Any help or advice would be greatly appreciated. We were thinking of selling them but if they are so rare and valuable, we may reconsider.

Thanks!!!
