Thieves stole an estimated $963,000 in trading cards from a FedEx truck outside PSA’s headquarters in Santa Ana, California.

Police said two full pallets and part of a third were taken. It could rank among the hobby’s largest heists.

The haul included sports, Pokemon and other cards already graded by PSA and on their way back to customers.

PSA says it deactivated the stolen cards’ certificates and alerted marketplace partners to watch for rare items.

The company has contacted affected customers and begun arranging compensation based on fair market value.

Police say the estimated value could rise as owners keep checking what disappeared from their orders.

A crowdsourced list of claimed cards reached 383 items, including a 1995 Upper Deck 23K Gold Michael Jordan card.

One collector said he lost 104 cards built up over two years, insured for $156,000, below what he believes they are worth.
