Fred Santore Jr., the box office treasurer at the Richard Rodgers Theater, where “Hamilton” opened in August, said that in his 34 years there this was the first time he had seen “any counterfeit tickets to a show.” Since August, about five times a week, the theater has had to turn away people bearing fake tickets, he said on Friday. (A few hours later, a photographer for The New York Times witnessed two people in line for the evening’s performance — strangers to each other — learn that their tickets were fake.)

Jason, 42, said in an interview last week that he had a healthy skepticism of Craigslist, but he had used the website to buy tickets to other New York City events. An ad there for “Hamilton” tickets appeared genuine, and the asking price — not too high, not too low — seemed appropriate.

He wrote a seller who later said his name was Dan, who agreed to sell him two tickets to the Jan. 2 performance. They met outside the Urban Outfitters store on Avenue of the Americas near 14th Street. Dan, who appeared to be in his 30s, arrived and chatted about how he had already seen “Hamilton” with his fiancée, so when they received tickets as a Christmas gift, he decided to sell them. He handed over a Ticketmaster envelope containing two tickets and a receipt, counted out the $600, said goodbye and strolled north.
