Calling Minnesota an epicenter for crooked coin dealers, federal authorities have filed charges against three more alleged swindlers.
The total taken in the three unrelated cases topped more than $2 million, prosecutors said, much of it stolen from elderly victims.
"Since the early 1990s, Minnesota has been a haven for coin fraud," U.S. Attorney Andy Luger said Monday. "The list of unscrupulous coin dealers is long and sad. These cases represent only the most recent examples."
The three men charged are Dennis Charles Helmer, 53, of Farmington; Tory Evan Hughes, 44, of Minneapolis, and Chrysanthos Nicholas, 55, of Mettituck, New York. Nicholas allegedly defrauded a client from Merrifield, Minn., eight miles north of Brainerd.
The largest fraud case involved Helmer, who was known by several names — Jeff Jones, Mr. Diamond and Dennis Dimon. He devised a scheme that scammed his victims of $1.2 million, federal prosecutors said.
The Helmer case is the first significant investigation since 2013, when Minnesota became the first state to pass legislation targeting unscrupulous coin dealers, according to the state Department of Commerce.
The new laws require bullion coin dealers to obtain a license and a surety bond. In addition, it also requires those who own a coin business or work directly with the public in selling or buying bullion coins to pass a background check.
"No longer can scam artists use bullion coins or collectible coins as an avenue to steal money in Minnesota," said Commerce Commissioner Mike Rothman.
