In 1996, Fleer/SkyBox introduced the Rubies parallel to SkyBox Premium products, adding modest hints of red foil to the cards. But the following year, SkyBox dug deeper into the mine to revitalize the parallel with a touch of rarity. The 1997 SkyBox Premium football set saw the debut of the now-classic /50 Ruby parallel.
The concept was inspired by star ruby gemstones that feature a unique internal star-shaped phenomenon called an asterism, making a star ruby featuring prominent color, cut, clarity, and carat among the scarcest gemstones on the planet.
That rarity carried over to football cards such as this Brett Favre #1SR. With a print run /50, this represents one of the quarterback's rarest playing-days cards.
The certification number on this card has been checked against the third-party grader's online database and is active as of 05/08/2026.
