The 1973 50p piece was the very first commemorative coin since decimalisation. It was introduced and issued by The Royal Mint to celebrate the UK's accession to the European Economic Community.
It features nine hands clasping each other in a circle, symbolising the nine member states of the community. David Wynne designed the coin, and it is intended to represent the trust, assistance and friendship which comes with EEC membership.
The proof 50p is presented in a capsule.
