Glenn of California by Richard Thompson Bedroom Set

My grandmother bought this bedroom set which includes a long dresser, Gentleman's Chest, and two nightstands in the 1960s/70s.  They are Glenn of California by Richard Thompson and in pristine condition except for the tambour doors on the Gentleman's chest which have ripped slightly and one handle came off (still have the handle though). I've attached images.  My grandmother is moving into an independent living senior community and doesn't need this second bedroom set so I'm hoping to get an idea of how much it's worth!  Thanks!  

Good
