1992 Cook Islands 50 Cent
In 1992 the Royal Australian Mint struck 50c pieces for the Cook Islands. Most of the 50c pieces struck used the new turtle reverse design by Horst Hahne which had been introduced in 1988. For unknown reasons a small number of 50c pieces were also struck using the old bonito fish reverse design by James Berry, which had last been used in 1987.
The re-use of the old dies was limited - from a sample it appears that about 7.7% of 50c pieces struck used the old design.
