The Half Penny was abolished in the UK in the year 1984. The decision to eliminate the Half Penny was primarily driven by economic factors. The cost of producing and maintaining the Half Penny had become more expensive than its actual value. Additionally, the Half Penny had lost its practicality in everyday transactions, as its purchasing power had significantly diminished over time. As a result, the decision was made to discontinue the Half Penny in order to streamline the currency system and reduce costs.
