As if Canada Post's stamps weren't enough to celebrate the Toronto roots of Superman on his 75th anniversary, the Royal Canadian Mint has unveiled a series of seven collector coins to commemorate the occasion.

While Superman was created in 1933 by Jerry Siegel and Joe Shuster when they were teenagers living in Cleveland, Shuster was actually born in Toronto, and lived there until age 9 or 10. He worked as a newspaper boy for the Toronto Daily Star, whose building served as a model for the Daily Planet (originally called the Daily Star).

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

The coins, which are available beginning today, depict different moments in the Man of Steel's history, but they're all engraved with the phrase "75 years of Superman," written in Kryptonian: There's the $75 14-karat gold coin ('the early years"), featuring Joe Shuster's illustration from the cover of Superman #1; the $10 fine silver coin ("vintage"); the $15 fine silver coin ("modern day); the $20 fine silver coin ("Man of Steel"), featuring Jim Lee's cover for Superman #204; the $20 fine silver coin with the iconic S shield; the $20 fine silver ("Metropolis") -- appropriately enough, "the world's first coin to feature an achromatic hologram"; and a "Then and Now" coin and stamp set, with a coin that shifts between Shuster's Superman #1 and Lee's modern reinterpretation.
