Bon Jovi's concert in Central Park this Saturday is free. But that isn't stopping some scalpers from selling tickets for as much as $1,500 a pair — despite a warning they cannot be resold.

New York City has distributed 60,000 tickets, with each person limited to two freebies. The performance is billed as a prelude to the July 15th All-Star baseball game, which will highlight the final season at Yankee Stadium.

The New York Post reports that it found 267 listings for tickets on eBay Monday. Prices ranged from 99 cents to $1,500 a pair.

Kimberly Spell, a spokeswoman for NYC Marketing, says lawyers will be contacting eBay officials to make them aware of the situation.
