Do Bristolians support the royal family? Operation Golden Orb Committee are the group who organised the coronation of King Charles. It has been estimated that the event cost around 100 million pounds. This is despite the number of guests at Westminster Abbey being capped at 2,000 which is less than a quarter of the 8,251 who attended Queen Elizabeth II’s coronation. Queen Elizabeths coronation cost around 1.5 million, which would equate to around 50 million in todays money which is roughly half of what King Charles’ has been estimated to cost
