Esperanto by Drexel credenza

I have a small credenza/cabinet that I would love to know if it may have some value! It has a slate top with a fancy design etched into it and a cool pattern on the doors. It looks in excellent condition to me, no dents or major signs of wear.

Here are the dimensions:
44" wide
29.5" tall
12" deep
Interior shelf is about 8" deep and is not adjustable

The stencil on the back says:
481-443-6
