Sports Card App CollX Bringing High-Tech to an Old Favourite Pastime

An idea taking flight: Father and son Ted Mann and his 10-year-old son Charlie, looking for deals at a recent sports card collectors show. The Philadelphia residents came up up with the idea for CollX - an app for sports card collectors that lets those on it know the value of their cards. The app was launched in January, and has more than 40,000 collectors on it and 15 million cards pictured, so far. Photo courtesy Ted Mann

A sports card app that was inspired by a 10-year-old boy after he and his 7-year-old brother discovered their dad’s collection in the basement of their home, is growing in value for collectors around the world.

For those who lost their shoeboxes full of sports cards when their mother threw them out when they weren’t looking, they likely now know a valuable piece of their childhood—both sentimentally and monetarily—was lost forever.
