1970 Captain Cook 50 Cent Date Varieties
In 1970 the Royal Australian Mint issued its first commemorative coin - the Captain Cook 50c piece. Curiously, it was also the first Australian decimal coin to exhibit date varieties.
On some 1970 50c pieces the 7 in the date is parallel with the rim while on others the 7 in the date is not parallel with the rim. Neither variety is rare although the 7 not parallel with rim is more common, accounting for around 65% of circulating coins, while the 7 parallel with rim is less common, account for around 35% of circulating coins.
It is unclear if both date varieties occur in mint or proof sets or in the specimen 1970 Captain Cook 50c pieces.
