Keep an eye on your wallets, guys.
Harry Kane was England's hero in the 2018 World Cup. Although we didn't quite make it to the final in the end, Kane won the Golden Boot for the most goals scored (6) of any player in the tournament.
He's given one to Harry Kane himself, one to the FA and he's putting the remaining four into circulation around the UK. Graham spent the first of the notes in the West Midlands village of Meriden. The second he spent in the Edinburgh cafe where J.K. Rowling wrote much of the Harry Potter novels.
The third has been spent in Merthyr Tydfil in Wales and the fourth was spent in Northern Ireland.
Graham had previously distributed similar notes with Jane Austen's face etched on - which ended up being worth a massive £50,000. The Kane notes are now estimated to be worth £20,000 each but this could rise even further.
To be in with a chance of winning, you'll need to look out for a three-eighths-of-an-inch drawing of Harry Kane's face on your fivers - so pay attention when you're spending!
