Arsenal fans were being charged up to £2,300 for black market FA Cup final tickets - 50 times face value of the cheapest official tickets.
Online touts are cashing in on huge demand from supporters desperate to see their club try to end a nine-year trophy drought against Hull on Saturday.
The Football Association stands accused of driving fans towards touts with their meagre ticket allocations to the two finalists.
Wembley Stadium has a capacity of 90,000, yet Arsenal and Hull has each received just 25,000 tickets.
Arsenal alone has 42,000 season ticket holders and its average attendance at the Emirates Stadium this season was over 60,000.
The remaining 40,000 tickets have been taken by Club Wembley members and distributed to what the FA describes as "the football family" including county associations and corporate sponsors.
The FA's controversial policy means that each year tens of thousands of diehard supporters miss out on their team's showpiece final.
The official tickets have a face value ranging between £45 and £115.
But Madrid-based agency 1st4footballtickets.com is offering final tickets at up to £2,300, including over £600 in booking fees and taxes.
Its most expensive tickets are said to come with full hospitality.
But even simple seats in the corner of the Arsenal section without any hospitality cost £1,160.
Similarly, agency ticket4football.com is offering final tickets at up £1,850 each, including £330 in fees and taxes.
The firm is based in Murcia, Spain with any legal disputes to be heard in a Spanish court.
Arsenal took over 49,000 fans to their semi-final after Wigan returned some of their unwanted tickets.
