By the time Dennis Helmer is eligible to get out of federal prison, many of his elderly victims likely will be dead.
A federal judge in Minneapolis on Tuesday sentenced the 54-year-old coin and bullion dealer from Farmington to more than 12 years behind bars and ordered him to pay $1.3 million in restitution.
"The dollar amount, I don't think will be an issue," Helmer said. "I have no assets now, but I do think I'll be able to do it."
U.S. District Judge David Doty said he hoped Helmer was right.
"I'm a bit skeptical about that," he added dryly. Then he sentenced Helmer to 150 months in prison, followed by 3 years of supervised release.
Helmer, who has three prior convictions for defrauding coin clients, preyed on mostly older, often sickly investors seeking a safe harbor from the stormy stock market. He built his businesses using a massive customer database that he took from other Twin Cities brokerages where he'd worked as a young man.
Helmer told the Star Tribune in 2012 that he had sold the list countless times to other precious metals brokers. Some turned out to be drug and alcohol abusers like himself who fleeced their clients. Versions of the customer list, which sold for $200 to $4,000, traded so widely that they came to be called the "DH leads," after Helmer's initials.
Tory Hughes, who ran Reputable Rare Coins in Roseville, relied on such leads to bilk more than $700,000 from his own clients and was sentenced last week by a federal judge in St. Paul to 71 months in prison. Several other former Twin Cities coin dealers also await sentencing in federal court.
