Fake Cash at a Handover: How to Check Notes on the Spot

Cash is the default in private sales because it cannot be reversed. That is true, and it is also why the counterfeit risk lands entirely on the seller. A bank transfer can be traced and disputed. A fake £50 in your hand is simply your loss, because a counterfeit note has no value and cannot be reimbursed.

The good news is that UK notes are unusually easy to check, and it takes about five seconds per note.

Every current UK note is polymer

Paper £20 and £50 notes were withdrawn from circulation in September 2022, and the paper £5 and £10 before them. Every note currently in circulation is polymer, which is a plastic film rather than paper.

That single fact removes a lot of work. If a note feels like paper, stop. It is either a withdrawn note that no shop has to accept, or it is fake. Both are your problem to solve, not the buyer's, once they have gone.

Notes featuring King Charles III entered circulation in 2024 and are legal tender alongside notes featuring Queen Elizabeth II. Both are fine. A note being an older design is not itself a warning sign.

The four checks, in order of speed

1. The see-through window. Every polymer note has a clear window with a detailed portrait printed in it. Hold it up to the light. The window should be genuinely transparent and part of the note itself, not a patch stuck on, and the printing in it should be sharp. Fakes very often get this wrong, because it is the hardest feature to reproduce cheaply.

2. Feel the raised print. Run a fingernail over the words "Bank of England" on the front. The ink is raised and you can feel it. Fakes are usually flat.

3. Tilt it. The foil patch changes as you move the note, and the colours shift. A printed imitation stays static.

4. Check under UV if you have it. Under an ultraviolet light the note's value appears in bright ink while the rest of the note stays dull. A cheap UV torch costs a few pounds and lives in a pocket.

The Bank of England publishes the current, definitive checks for each denomination with photographs at bankofengland.co.uk. Features change with new designs, so check there rather than trusting any single article, including this one.

The tricks that show up in private sales

• The rush. A buyer counts fast, talks continuously, and hands over a bundle while you are distracted by the item. Slow the whole thing down. Count in silence.
• The good notes on the outside. A wad with genuine notes top and bottom and fakes in the middle. Check every note, not the outside two.
• The large denomination. £50 notes are handed over far less often in daily life, so people are least practised at checking them. That is exactly why they are used.
• The recount. A buyer takes the cash back to "recount", removes a note or swaps one, and hands it back. Once the money is in your hand it does not go back into theirs.
• The evening meeting. Poor light makes every check harder. Meet in daylight, or somewhere brightly lit.

What to do if you are handed a fake

Do not hand it back and let the person leave, and do not try to spend it. Knowingly passing on a counterfeit note is a criminal offence, so once you know it is fake it becomes your problem the moment you pass it on.

If you are certain a note is counterfeit, keep it if it is safe to do so, note anything you can about the person, and report it to the police on 101. If challenging someone would put you at risk, let them go and report it afterwards. A phone is replaceable and so is £50.

Counterfeit notes handed in at a bank are sent to the National Crime Agency and are not reimbursed, which is worth knowing in advance so the decision is not a surprise.

Reducing the risk before you get there

• Meet at a bank during opening hours and pay the cash straight in. The counter will spot a fake immediately, and you find out while the buyer is still in front of you. This is the single most effective thing on this page.
• Prefer a transfer you can see clear in your own banking app, not a screenshot. See the safest way to get paid in a private sale.
• Meet somewhere with cameras and people, which is covered in where to meet a buyer safely.
• Know who you are dealing with. Almost every counterfeit handover depends on the person being untraceable afterwards.

That last point is the one nothing else on this list solves. Chainr verifies both people with a government ID and face check before you meet, keeps a card and address on record for each side, and leaves you both a timestamped certificate of the sale. Someone who has proven exactly who they are, in a record that outlives the meeting, is not the person who hands over a bad £50.
