COIN hunters are now on a mission to track down the 26 new 10p coins - and some of them could be worth up to 240 TIMES their original value.
The Royal Mint has released a new line of 10p coins - one for every letter of the alphabet - to celebrate everything that makes Britain great.
The mint says the idea behind the new coins is to mark the best of Blighty and it hopes lots of the public will join in the hunt themselves.
Some 2.6million coins have been minted - 100,000 for each letter - meaning that demand, and potentially the coins worth, could be massive.
And we reckon that the letters E, T, I, O, A and S are going to be worth the most. Now, we don't know for sure but we've got a pretty good theory.
We think some collectors are more likely to want letters that mean something to them, like the first letter of their name or spell out words important to them, as well as collecting the whole set.
And if the value of the Kew Gardens 50p coin is anything to go by then these could be worth up to 240 times it's value too.
It's the rarest 50p piece, with only 210,000 of them released into circulation in 2009. Now they're selling for up to £140 on eBay.
MAKE A MINT Royal Mint sparks coin hunt with 26 new 10p coins spelling the A-Z of Britain – but are they worth anything?
So if our theory is correct, some of the new 10p letter coins could be worth up to £24 EACH if they prove to be popular enough.
We've spoken to the word boffins over at Oxford Dictionaries who told us that 'E' is the most commonly used letter in the alphabet.
The inventor of Morse code, Samuel Morse, came up with the stats back in the 1800s who found that 'E' came up 12,000 times, with the next most used letter being 'T' with 9,000 times.
But 'E' more commonly comes up in the middle or end of the word, including names, like in Chloe, James or Oliver.
The wordsmiths also found in their 2004 research that words are most likely to start with 'S' meaning that it's probably going to be sought after by people wanting to spell their names with the coins.
A-Z of Britain in coins - what do they represent?
THE coins have been designed to represent the best of Britain. With 10 of them decided by a public vote. Here's what each one represents.
- A – Angel of the North
- B – Bond…James Bond
- C – Cricket
- D – Double Decker Bus
- E – English Breakfast
- F – Fish & Chips
- G – Greenwich Mean Time
- H – Houses of Parliament
- I – Ice-Cream Cone
- J – Jubilee
- K – King Arthur
- L – Loch Ness Monster
- M – Mackintosh
- N – National Health Service
- O – Oak Tree
- P – Post Box
- Q – Queuing
- R – Robin
- S – Stonehenge
- T – Teapot
- U – Union Flag
- V – Village
- W – World Wide Web
- X – X Marks the Spot
- Y – Yeoman
- Z – Zebra Crossing
And according to letterfrequency.org, 'E', 'I' and 'S' are the most common letters to turn up more than once in a word.
The language database also puts 'T', 'O' and 'A' as the most common first letters in English words.
Are you still with us? It sounds complicated but if our theory turns out to be correct, the coins could be worth a small fortune.
Basically, based on what the most popular letters in the English language are, we reckon coins with the letter E, T, I, O, A and S are going to be the most valuable to collectors because more people will be needing them.
Rare coins can sell for up around 10 to 12 times their value when they're sold on, while this month a completed Olympic 2012 set sold for £35 on eBay.
Sellers are also flocking to the Royal Mint to pick up a 2018 50p which celebrates Sir Issac Newton and is being sold for more than £60.
And this month, the Change Checker website launched a new tool which reveals how much your spare coin could be really worth.
