It's a bird, it's a plane. No, wait ... it's a commemorative collector coin.

To honour the 75th anniversary of Superman -- co-created by Canadian Joe Shuster and his American collaborator Jerry Siegel -- the Royal Canadian Mint has released seven new coins, each depicting a different moment in the superhero's history since the character was sold to D.C. comics in 1938.

The coins were unveiled at Yonge-Dundas Square Monday.

“The generations of young people who grew up reading Superman comics may not have fully appreciated the story behind them,” Citizenship and Immigration Minister Chris Alexander said. “Our government celebrates Canada’s history and heritage and the very values and strengths that Superman embodies.”

The most expensive coin, of which only 2,000 are being made, is cast in 14-karat gold and will set you back $750. The cheapest buy is a cupro-nickel coin-and-stamp set for $29.75.

Some of the coins feature the words "75 years of Superman" engraved in Superman's native language, Kryptonian.

The coins can be ordered directly from the Mint at 1-800-267-1871, from specialty dealers, participating Canada Post outlets or online at mint.ca/superman.
