This is a 2015 Canadian $20 fine silver coin from the Royal Canadian Mint's "Iconic Superman Comic Book Covers" series. The reverse side of the coin features a colorized recreation of one of the variant covers for the DC Comics issue Superman Unchained #2, which was released in 2013.
This coin depicts Superman using incredible strength to lift a tank over his head with one arm while battling a military force. The design utilizes meticulous engraving and vibrant color to replicate the original comic book artwork by Jim Lee.
