Old English Street Lamp post

An old man gave it to me at a garage sale - he said it was 300 yrs old and that he had it for years but wanted it gone now so he gave it to me. I have no use for it. It needs a bit of repair and the glass needs replacing on the bottom but other than that it would make a really cool novelty lamp for someone. DOES ANYONE KNOW THE VALUE OF THIS LAMP? I am willing to sell it but i have no idea what to ask for it. Thank you!
