“Storage Wars” star Dan Dotson said he just discovered that he sold a storage unit containing $7.5 million in cash for a measly $500.

Dotson and his co-star wife Laura told The Blast that a random woman approached him at one of his auctions about the multi-million dollar finding last week.

“She walked up and told me her husband works with a guy who bought a unit from me for $500 and found a safe inside,” Dotson said.

The woman said the new unit owner, who wasn’t identified, took the safe to a locksmith who broke it open and discovered $7.5 million in cash.

Things got complicated when the new owner was contacted by an attorney representing the former owners, who offered a $600,000 reward in exchange for the cash.

The new owners declined the initial offer before settling on $1.2 million to return the remaining $6.3 million.

The Dotsons’ co-star, Bargain Hunters Thrift Store owner Rene Nezhoda, said the cash was most likely mafia or drug cartel-related.

“If you find money like that, there’s probably a reason it isn’t in the bank,” Nezhoda told The Blast.
