Margrethe II 20 Kroner

These coins were struck in 900 fine gold, a rarity for Danish currency post-World War II, often commemorating events like Queen Margrethe II's silver jubilee in 1977.

That purity level made them prone to wear, even in proof sets, which surprised more than a few collectors who expected immortality from gold. Designs varied by year, featuring motifs from royal anniversaries to national milestones, all overseen by the Royal Danish Mint.

Exact mintages remain murky; records from the 1970s weren't always meticulous. Still, variants exist for events such as the 1980 Olympic Games in Moscow, though Denmark's participation was boycotted.

Some years saw recycled planchets from earlier issues, a practical touch in an era of economic caution.
