The decimal New Half Penny and Half Penny coins were last issued for circulation in 1983 and were withdrawn from circulation and demonetised in December 1984. So, unless they are part of a Proof or uncirculated mint set or are individual Proof or uncirculated coins and in absolute mint condition, they have little or no value. The 1984 Half Penny was only issued as part of a Royal Mint Uncirculated or Proof set. A British 1984 bronze Half Penny coin (Elizabeth II), uncirculated and in absolute mint condition could fetch up to £2 GBP. A British 1984 bronze Half Penny coin (Elizabeth II)(Proof), uncirculated and in absolute mint condition could fetch up to £2 GBP.
