I've sold some expensive items for cash and I now have a few thousand in £50 notes. Can I pay this into the bank? It's less than £5000 but my income is low so I think it will look dodgy and trigger something. I have the emails from the retailer from when I bought the items new but I don't have any paperwork from the buyers I have just sold the items to. I have never done this before. I could have sold the items a few years ago and got a lot more money for them but I was worried about this situation arising so I procrastinated. Now here I am in the same situation.
