Like most of the other brands involved in sports cards today, Donruss was started as a candy/confectionery company and evolved into trading cards. The brand has passed through the hands of a number of companies, and has been a property of Panini since 2009. The company was renamed Panini America after the purchase, but the Donruss brand name still lives on with licensed NFL and NBA, along with unlicensed MLB products.
As the Donruss brand is lower tier to Panini in both basketball and football, and their baseball being unlicensed, they’re one of the less popular brands with serious collectors. They tend to be a more economical way to get a card of your favorite player.
