The Kew Gardens 50p is the rarest British coin in circulation. It's the ultimate find in the Great British Coin Hunt, and by some small miracle I managed to find one in my change a couple of years ago! It depicts the Great Pagoda at Kew Gardens, encircled with vine and the word 'Kew' beneath. 'A Great British Adventure' is a series of videos that have taken me all over the UK. The videos are based on the new A-Z 10p coins - they aren't videos about the coins, rather, they use them as a sort of contents page. Instagram: @halfasleepchris
