The second most expensive tournament was the cricket World Cup New Zealand hosted last year. The average price for a ticket was $248.
Football's World Cup in Brazil cost an average $231 per seat, adjusted for inflation, and the 2012 Olympics $214 per seat.
More than 2.3m tickets have been sold, with only only 50,000 still available through official platforms. But tickets for next Friday's sell-out opener between England and Fiji at Twickenham were last night quoted at $2019 on one unofficial website.
Organisers are urging fans to purchase tickets only through the official World Cup website - tickets.rugbyworldcup.com.
