20 Dollars - Elizabeth II Superman Action Comics #1

Action Comics #1, published in June 1938 by Detective Comics Inc., introduced Superman and effectively created the superhero genre as a commercial category. The issue sold for ten cents on newsstands; a preserved copy sold at auction in 2014 for $3.2 million. The Royal Canadian Mint's licensing agreement with DC Comics produced this piece under a broader commemorative program that ran across several years, pairing fine silver bullion with pop culture IP — an increasingly common revenue strategy for sovereign mints facing declining circulation mandates.
