Grimsby chairman John Fenty has revealed that reaching the Johnstone's Paint Trophy final at Wembley has netted the club around £400,000.
Fenty is delighted with the cash the Trophy has generated for Town
The Mariners have been given roughly 25,000 tickets for their 30 March Wembley date against MK Dons.
Fenty told BBC Look North: "Broadly speaking this competition from start to finish is probably going to be worth around £400,000.
"Wembley will bring enormous new income streams to the football club."
Fenty said the money is massive for the club and the town of Grimsby.
"We are all very, very proud of what the team's done and what the football club has achieved.
"The town is buzzing and the football club is once again on the map and we are delighted to say that."
Town have been given the East side of Wembley stadium, and will be allowed to wear their home black and white strip after the Football League ruled that it would not clash with MK Dons' home strip.
