A lottery jackpot from the early ’50 and ’70s could be worth as much as $3 million if the winning bid comes from a former resident of New Jersey, the owner of a New York City bar and restaurant said on Wednesday.

The winner of the $100,000 ticket to the lottery from 1951 to 1953 could be from Jersey City, the former home of the Brooklyn Dodgers, New York Mayor Michael Bloomberg said on Twitter.

Bloomberg said the winning bidder, a retired real estate agent, “may be an old friend” of the owner.

The jackpot could be huge because a $3,000 bet on a $1,000 drawing would yield $6,400, he said.

The winning bid for the ticket, if confirmed, could be as high as $5 million.

“This is a very rare chance,” Bloomberg said in a tweet.

“This is what the lottery is all about.”

REUTERS/Kacper PempelAuctions for the lottery ticket, which sold for $1.2 million in 2009, are expected to begin in mid-January.

It is not yet known whether the winning bidders have a relationship with the bar, Bloomberg said.

“We are aware of this,” a spokesman for the New York Attorney General’s office said in an email.

“We have contacted the seller and have asked for his cooperation.”

A person who answered the phone at the New Jersey Lottery told Reuters he did not know whether the ticket belonged to a former person or if it belonged to someone who was living in New Jersey.

The owner of the bar is listed as “Mr. William R. Niederhoffer,” according to the New England Historical Society, which maintains the lottery records.

Niederhorners bar is located in the historic East River waterfront district of Greenwich, New Jersey in the borough of New York.
