| Additional information |
The 1988 pattern was struck by the Royal Australian Mint as part of internal trials exploring a redesigned 50-cent piece to coincide with Australia's bicentenary celebrations. The existing dodecagonal format was never seriously threatened — the change went nowhere — but the exercise produced a small number of trial pieces that escaped into collector hands through the secondary market rather than any official release program.
