When Frank Costello died in 1973, he wasn't exactly the "Boss of All Bosses" anymore. He’d been sidelined, shot in the head, and essentially forced into a quiet retirement. But the guy known as the "Prime Minister of the Underworld" didn't go out broke. Far from it.
If you're looking for a simple number, most historians and financial records peg the Frank Costello net worth at death at somewhere around $52 million. Now, before you compare that to a modern-day tech mogul, remember we are talking about 1970s dollars. In today's money, that's well over $350 million.
But pinning down a mobster’s bank account is kinda like trying to nail Jell-O to a wall. Most of his "wealth" wasn't sitting in a Chase savings account. It was buried in real estate, layers of "legitimate" businesses, and probably literal cash in safes that the IRS never got to smell.
The Reality of Frank Costello Net Worth at Death
Frank wasn't like the flashy gangsters you see in the movies. He didn't walk around with a gold-plated Tommy gun. He wore custom-tailored $400 suits and preferred the company of judges and politicians to street thugs. This "legitimate" veneer is exactly why his net worth was so substantial at the time of his passing.
By the time his heart gave out at age 82 in a Manhattan hospital, Costello had spent decades perfecting the art of the "silent partner." He wasn't just a racketeer; he was a sophisticated investor.
Where the Money Actually Was
Costello’s wealth was a cocktail of old-school vice and high-end real estate. Honestly, the breakdown of his assets at the time of his death looks more like a diversified hedge fund than a criminal enterprise:

- Real Estate Holdings: He lived in a massive, nine-room penthouse at 115 Central Park West (The Majestic). This wasn't a rental; it was a power statement. He also owned a sprawling estate in Sands Point, Long Island, where he spent his final years growing flowers.
- The Slot Machine Empire: Decades earlier, he’d controlled tens of thousands of slot machines in New York. Even after Mayor La Guardia started dumping them into the Hudson River, Costello just moved the operation to Louisiana and New Orleans with "Dandy Phil" Kastel. That stream of income never truly dried up.
- Vegas Interests: Costello had deep roots in the early days of Las Vegas. When he was shot in 1957, police found a slip of paper in his pocket detailing casino wins from the Flamingo. Even in "retirement," those points in casinos kept paying out.
- Wall Street Investments: Unlike his rival Vito Genovese, Costello was smart enough to put his money into the American economy. He had significant holdings in oil, real estate, and even poultry distribution.
The IRS and the Paper Trail
One reason the Frank Costello net worth at death is so debated is because of his constant legal battles. The man was a ghost to the taxman for years. In the 1950s, the government finally caught up to him for tax evasion—proving he’d spent roughly $100,000 more than he’d declared in income over a four-year period.
To you and me, $100,000 sounds like a lot. To Frank, that was probably the rounding error on a single weekend’s bookmaking.
During his probate hearings after February 1973, his official estate was valued significantly lower than the $52 million figure often cited. This is a classic mob move. You don't leave a paper trail that leads the Feds straight to your wife and heirs. Most of the wealth had likely been shifted into private trusts or "ghost" companies long before he took his last breath.
Why the $52 Million Figure Sticks
You’ll see that $52 million number pop up in almost every financial retrospective of the 20th century’s biggest criminals. It places him significantly lower than guys like Pablo Escobar or Amado Carrillo Fuentes, but for a "retired" mobster in the 1970s, it was astronomical.
What most people get wrong is thinking he lost it all after the attempted hit on his life in 1957. While he did cede control of the Genovese crime family, he kept his "associates" and his personal investments. He was a consultant. People paid for his brain, not his muscle.

A Legacy of "Quiet" Wealth
Costello’s death didn't trigger a massive auction or a public seizing of assets. He’d played the long game. While other mobsters were dying in hail of bullets or rotting in Alcatraz, Costello was sitting in his Sands Point garden, probably laughing at the IRS.
He was the first "CEO Mobster." His net worth wasn't just a reflection of crime; it was a reflection of his ability to integrate crime into the fabric of American business.
