Last summer I was given this little object by my PhD supervisor. As he handed it to me he noticed a puzzled expression on my face. The object, a champagne cork and pound coin, was one that I had not encountered before.
In fact, the practice of placing a coin in a champagne cork has a long tradition. Corks that have been popped on special occasions, at weddings, birthday parties, or in this case my PhD viva (the examination of my doctoral thesis), have been made into keepsakes and good luck charms by many people.
They were also once used by fishermen, who would cut a slit in the cork floats on their nets and insert a coin to pay for their catch. This one now sits on a shelf in my office, where I hope it will work a little lucky magic.
I hope you will share your own lucky objects with us by entering the Amulets Around The World Today photograph competition, which runs from 10 May to 31 July 2012.
