What can you do with old banknotes? Contact me for advice on what to do with old British banknotes. I can value them. I can offer to buy the bank notes. Old banknotes can be worth very little or the old banknotes can be valued at a decent price. Ring me on 0759 257 8096 for a chat. I started collecting banknotes when I found a small collection in the bottom of a box of postcards. One old note sold for over £100. I was hooked. I bought ‘English Paper Money’ and from then I began collecting banknotes steadily. So, feel free to contact me by phone or email and perhaps the old banknotes can turn into money in your pocket!
