Antique Trunk of manufacturer Chas. G. Wilt. Chicago?

It was manufactured in 1862. It was my grandfather's. Inside the trunk it says Chas. G. Wilt Trunks Chicago. I have been looking all day on the internet to see if it is worth keeping as an antique, but can't find any information. I also found ration stamps from 1955 inside the trunk, but never heard of the person would signed the booklet. Can someone please point me in the right direction as to where I can find out if it is worth anything?? Thanks!!
