Thanks for answers and sorry for being maybe unclear with the question, but I have couple of old barrels, english ones, and I'm trying to find some market value of them. It's not for insurance, it's just I wanna know information how much is their value.
Once I've found the web page from some company from England with offer that you have to fill up informations they need for appraisal and also send a pictures of the piece, so that they can be more specific. I remember they also charge that service around 30 pounds. Maybe I'm trying to find impossible, but when you don't know information about, in my case that old english barrels, you don't know their value and also don't know for how much to offer them.
