How can I ship a rocking chair?

The item is a large antique rocking chair of solid oak that was my grandfather’s. My late mother’s household is now, three years after her death, being broken up and the treasures distributed among her children. The chair is mine if I can claim it and remove it.

I can’t go there in person, but someone can go on my behalf.

I am on the West Coast and the rocking chair is on the East Coast. By what means could I have it shipped? How would I arrange that? A moving van for the one item does not seem practical to me. What are my choices?
