Sending Your Cash

We have listed some helpful tips & tricks about sending your leftover coins and banknotes in the mail. If you apply these few simple rules, the risk of anything happening with your shipment is as small as if it were a normal letter, a birthday card or an invoice.

If you are sending currency worth over £20, €20 or $20, we recommend that you use a recorded delivery service, like Royal Mail Signed For®TNT Express® or USPS Tracking®. It will enable you to track your shipment and it will provide you with a proof of delivery.

If you are sending currency worth over £50, and if you are sending from within the UK, you should use Royal Mail Special Delivery Guaranteed®. For international high-value deliveries, we recommend that you use a courier service, declaring the content as ‘documents’ (when sending banknotes).

If you are sending from the United Kingdom, and if the combined weight of the coins and/or banknotes is over 1kg, we can in most cases fully refund your postage costs. Please contact us prior to sending your currency to find out more.

In most countries it is perfectly legal to send money in the mail. In many countries it is common practice to put a few banknotes in a birthday card and send it in the mail. In the United Kingdom, the United States and in most European countries it is legal to send money in the mail, also if the money is sent overseas.

In some countries there are restrictions on sending money in the mail. These countries have laws in place that either forbid sending money through their postal network, or limit it to a maximum amount. If your country is in the list, please consult the applicable laws before sending money in the mail:

Cape Verde
Central African Republic
China (except Hong Kong and Macao)
Czech Republic
Dominican Republic
New Zealand
Saudi Arabia

We suggest that you use “LOC” instead of Leftover Currency. This way you don’t give away information about the contents of your letter/parcel. If you plan to self-deliver your currency, you can self deliver it to our Datchet office, or to our central London office, located at LOC 3rd floor 207 Regent Street, London W1B 3HH.

Coronavirus (COVID-19) update 15 March 2020: We advise against self-delivering into the Regent Street office in central London. We continue to receive post as normal in the Datchet office, either sent by post or self-delivered.

Include your filled out paper exchange form, or if you’ve used our online wallet, simply write the reference number you were given on a piece of paper and include this with your notes and coins.

If you are sending banknotes, put them in a promotional flyer or greetings card. Use a non-transparent (opaque) envelope. If you are sending many notes, think about using a cardboard envelope or padded envelope.

When sending from outside the UK-EU-EEA single market, consider using a regular letter envelope instead of a bubble foam envelope: bubble foam letters are treated by customs as parcels and you may have to pay a customs fee as a percentage of the declared value. Always use a bubble foam envelope if you are sending both banknotes and coins.


When sending coins, you must pack them securely. You want to make sure the coins don’t damage the envelope or parcel while in transit.

One way to do this is by fixing the coins to a piece of cardboard, using adhesive tape. Alternatively, you can use coin wrappers or tin foil.

It’s always a good idea to strengthen your parcel or envelope, using adhesive tape, especially the edges and corners.

If you send coins in a parcel, make sure the coins can’t rattle or move around by filling up the empty space with light materials, like plastic bubble wrap, foam, crumpled up newspapers or polystyrene packing peanuts.


When you send coins, or a stash of banknotes, it’s a good idea to fasten the envelope seal flap using adhesive tape. It is perfectly okay to tape your envelope: the seal, edges and corners are most vulnerable.

If you write your address on the back of the envelope, and cover it with transparent tape, it will be easy to see if the envelope has been tampered with, which is a strong deterrent against tampering.

Postage will vary, based on the size and weight of your package, and the delivery company you use. Most delivery companies have online postage calculators. Make sure you pay the full postage. If you don’t, your letter or parcel might be sent back because of postage due, or left for collection in the post office.

Ideally yes, include a return address to which your shipment can be sent back to if necessary. The address can be a PO box or a regular address. The return address is either written on the back seal flap of the envelope (UK and Europe) or in the upper left-hand front-side corner (United States).
