Those old sports cards in your basement may be worth something thanks to continuing boom of popularity for the hobby.

The pandemic helped usher in a newfound love for the hobby as millions of people are becoming reacquainted with their cards. One new craze is the practice of box breaking, where collectors purchase hundreds of packs of cards and open them live on social media channels in search of rare cards. One such YouTube creator, known as Packman, has 248,000 subscribers to his channel and has about 50,000 views every time he does it.

Things are a little bit calmer for Joe Miller, who has kept up with his card collection since he started in the 1940s. Miller and his friend Roy Sye will be showcasing some of his rarer items as a part of his sports card show in his garage in Baileys Harbor over the Fourth of July weekend. While some of the more modern practices do not appeal to him, Miller says getting back into card collecting remains one of the greatest decisions he has ever made.

Some of Miller’s cards date back to the early 1910s, including rare Hassan Triple Fold cards that feature three different sections that can be folded together.
