The feds believe 75-year-old William Coyman was ferrying drug money to Philadelphia when he collapsed last August, and they’ve asked a judge to give them the cash, sources said Thursday.

Meanwhile, a lawyer for Boston bank robber John Burke, who now runs an outfit called 180 Entertainment in the City of Brotherly Love, has filed a lawsuit in pursuit of the loot.

The lawyer, Steven DiLibero of Providence, R.I., has not explained what kind of business Burke runs or what the money was for.

But Coyman’s son, also named William, said his pop was a courier for the company and suspects it’s funny money. He also wants nothing to do with it.

“The people connected to that money are probably not good people,” he said Thursday. “That’s accurate.”

Investigators, however, are not sure if Coyman intended to deliver the dough — sources said he had an Amtrak ticket from Boston to New York, but no ticket to Philadelphia.

The mobster’s son, who now lives in northern California, said his dad’s unsavory connections have been “embarrassing my whole life” and declined to discuss this case.

“I really didn’t want to talk about this,” he said.

“My dad was a great man. But he had a colorful history.”

Did he ever.
