1927 Majestic White Rotary Sewing Machine with Cabinet (elect)

I have a 1927 Majestic White Rotary Sewing Machine with the Cabinet, its about waist high and in great shape considering its age. I just want to know what it is worth, or if its worth more to keep as a conversation starter and hand down a while longer. It is a wood cabinet, has electrical cord, and patented Nov. 6, 1927. I even have the motor number and needle size on it. It is black, with great gold detailing, but the name is just visible on the side of the machine itself. light still works, haven't really tried to see if its running cause i dont know where to start but just wondering what these go for or if i'd do better at an auction or on ebay. I have been unable to find much about it online anywhere .... if anyone knows i can get pics up later this evening.
