Value and Line of Imperial Table?

I inherited this Imperial marble coffee table. I believe it may be from the 50's judging by the logo, but not entirely sure. I was wondering what it might be worth and if there was a particular name for this line. I've seen a few Imperial coffee tables, but none that were marble. I also haven't seen any with this style of supports/legs.

The 'Imperial' logo is located on the underside of the table top. The marble section has a wooden frame under it and that just sits on the legs. There is no sign of any missing screws or bolts, but appears to just rest on the legs. Possibly, due to the weight of the marble, they didn't feel the need to bolt it together. (This is just speculation, but wanted to be as detailed as possible.) Any information would be greatly appreciated! Thank you!
