E.Hipkins & Co Safe

I am looking to get rid of a very old safe that I have in storage and originally thought of selling it on eBay but a few little piecws of information I picked up promted me to think that it may be quite valuble. It is made by E.Hipkins & Co of Kateshill Works, Dudley, UK. It's pretty old and has plenty of scratches and some rust to show for its time. Its dimensions are very approximately: Height: 2ft 9 inches Width: 2ft 4 inches Depth: 2ft 4 inches I was wondering if anyone knows the true value of this safe.
