It was this day in Rock History in 2019 The Cook Islands, a nation in the South Pacific, released two silver coins to honor two classic albums from this band. Who was it?

Answer:

It was the Greatest Rock Band in the World, AC/DC.  The band’s landmark 1981 album ‘For Those About To Rock (We Salute You) was honored on a two dollar coin while 1990’s ‘The Razors Edge’ could be found on a ten dollar coin. Both feature a portrait of Queen Elizabeth II on the reverse side.
