The Cook Islands, a sovereign state in free association with New Zealand, uses two official legal tender currencies. The New Zealand Dollar circulates in parallel with the local Cook Islands Dollar; at the same time, the government also authorises many legal tender coins in the Cook Islands Dollar currency for collector's purposes.
These coins come in various sizes, including the mini-coin one tenth of a gram of gold format - such as this one.
This gold foil "coin note" was issued as part of the coin series celebrating world-famous Australian rock group AC/DC.
AC/DC are an Australian rock band formed in Sydney in 1973 by Scottish-born brothers Malcolm and Angus Young. Although their music has been variously described as hard rock, blues rock, and heavy metal, the band themselves call it simply "rock and roll". The band's line-up varied throughout the years; it did not disband though, and issued its latest album in 2020, 47 years after it was founded.
The Mint says about the coin:
Printed precious metal banknotes have surged in popularity among collectors over the past years. This is why we created a special version to pay tribute to Angus and his band. "In Rock We Trust": this slogan embodies all what AC/DC stands for more than 45 years.
The note measures 156×67 mm and is minted from 1/10 gram of fine gold with a prooflike finish. Paper versions of banknotes that are similar to this were dropped from the ceiling by the thousands during their filming of the “Money Talks” video in 1990. You will also find links to their major hits incorporated on both sides of this golden laminated note. In fact, the notes merely measure a thickness like a sheet of paper.
