The promotion was launched at the home in Cadbury in Birmingham as part of the Bullring shopping centre’s ten-year birthday celebrations at the end of September. The activity will continue until 12 November.
Pretty Green Events was responsible for the security and logistics programme, which saw the golden bars and entertainers on the road to entertain shoppers in Bristol, Liverpool and London.
Passers-by were encouraged to have their photo taken with the solid gold Cadbury bars, and to tweet the hashtag #unwrapgold for a chance to win one of the eight gold-wrapped chocolate bars, which will see winners take home a real gold replica of the product.
There is also a one-in-eight chance of winning smaller prizes such as chocolate and cinema tickets.
Winners of the golden bars will also receive a consultation with a gold advisor on how to store or how to sell their prize, the exact value of which depends on the size and shape of the chocolate bar it is based on. This can mean that some of the gold chocolate bars are worth up to £22,000.
Sian Baker, head of experience at Pretty Green, said: "Cadbury is known for bringing a bit of magic into people’s lives so the Unwrap Gold tour was developed to do just that.
"We wanted to bring the promotion to the public in a typically Cadbury way – making it an engaging, immersive and most importantly, fun consumer experience.
"The tour gave fans the chance to enjoy their favourite chocolate bars and take part in the competition and we’re keeping our fingers crossed that soon we’ll meet our first golden winner."
