A late-night shopping spree in October 2020 saw Rob snap up a case of 2020 Panini Mosaic Choice cards. As the reality star couldn’t get down to his regular store – The Bullpen in Los Angeles – he asked them to open it up on his behalf, live on Instagram. There were some rare American football cards inside, including one of Justin Herbert and a Joe Burrow collectable.

However, the real gem was a Tom Brady (pictured) card. Experts have estimated that the card could be worth up to $250,000 (£183k), which is quite the profit given that Rob likely paid around $13,000 (£9.5k) for the entire case. It just goes to show that collecting cards can be a lucrative business.
