Drexel Heritage sectional early 60s

I'm trying to determine the value of a Drexel Heritage sectional purchased at an estate sale in Palm Springs a few years ago that I am now putting up for sale. The seller told me it was an Edward Wormley, but the price didn't even remotely reflect that and one dealer here in LA told me he didn't think it was a Wormly. Even so, it's a Drexel and in very good condition. The Drexel website says they won't authenticate uphostered furniture, so I'm not sure how to proceed to determine the price.

Measurements are 93" x 82" x 26" high. 6-piece sectional. Struturally in great shape, upholstery is in decent condition, though I would redo it if I were going to keep it.
