Humidor Stand

My grandmother just gave me this old humidor stand. She said it sat in the corner of her grandmother's bedroom for a long time, she was looking to get rid of it (I won't let her sell anything) so she gave it to me. She said it probably was her grandpa's [I said 'unless her grandma took up smoking cigars,' jokingly].
I found a little bit online about them (tell me if I'm wrong); they were made in the 1930s, made by furniture companies as small accessory pieces, made of a cheap wood that was used frequently back then, the humidor box is lined with some sort of metal with a white coating.
I've found that they're worth about $100, let me know if any facts that I have are incorrect or if there's anything unique about this humidor stand.
Thanks, anyone's help is appreciated
