Following the band’s chart-topping album «Number of The Beast», the pressure was on for Iron Maiden. However, their next release «Piece of Mind» in 1983 proved their ambition was unparalleled. Their 4^th album was a critical and commercial success, reaching number three in the UK album charts and going platinum in the UK and North America.

As a tribute to the 40^th anniversary of «Piece of Mind», Eddie, Iron Maiden’s mascot, is featured on three exceptional issues. On a 2-ounce silver, a half-gram gold and a 5-gram silver note, he fights his shackles as an imprisoned maniac.
