This is a 2015 Canadian $20 Superman Fine Silver Coin.
The reverse depicts Superman in a classic "Man of Steel" pose, about to take flight with his right arm raised and cape billowing behind him. The design is based on the 1980s DC Comics look and features the iconic "S" shield on his chest.
It was the first release in a series of silver coins celebrating DC Comics originals. It was part of the Mint's popular "$20 for $20" program, where coins were sold at their face value.
These coins are highly sought after by collectors of DC Comics memorabilia and numismatists.
