New Travis Court Collection by Drexel

I have a New Travis Court Collection by Drexel dining room set to include a table with 2 leaves, 6 chairs including a captain's chair, a china hutch and a server with a pull-out butler's tray. 

All of the pieces are in excellent condition save for 2 small scuffs on the top of the server (pictured) and a missing knob on the butler's tray (pictured). I am trying to find out the value of these pieces. Everything I have been able to find online (not much) has the value all over the place.

Here are the markings I found on each piece:
