"Fans can pay what they want between $5 and $50 to see Simon off," explained Warriors CEO Cameron George.
"If you think he's worth $20 you can pay $20 or if you think he's worth $50 you can pay that.
"We're putting the recognition for Simon first above and beyond any cash-grabbing exercise or anything like that given the nature of the game and occasion."
George hopes Warriors supporters and the wider New Zealand sporting public will show the same kind of enthusiasm for Mannering as Australians have in farewelling retiring North Queensland captain Johnathan Thurston.
A sell-out crowd of 25,000 turned out for Thurston's final game at Townsville's 1300Smiles Stadium for the Cowboys 44-6 win over Parramatta on Saturday.
Thurston's last appearance in Saturday's away clash against the Gold Coast has already drawn unparalleled interest with the Titans selling out Cbus Super Stadium for the first time in the club's history.
With Mannering having shown unwavering loyalty to the Warriors throughout his career by repeatedly turning down lucrative offers to join rival clubs, George is adamant anything less than a sell-out crowd would be a letdown.
"The public can come and pay tribute to one of the game's greatest and one of if not the greatest Warrior of all time," he said.
"We're giving fans and Kiwi sports lovers a chance to send off a national hero by paying what they think it is worth.
"Look at what Townsville did for Johnathan Thurston in selling out their stadium and the Gold Coast is already sold out for his last game and there's no difference in our view.
"Simon chose to stay and represent this club through hard times which represents New Zealand each week in the NRL as opposed to taking bigger offers to go and play for clubs across the Tasman.
"He stayed here to fight the good fight and now is our time to repay him and we want to fill the stadium up."
