"A successful Maple Festival provides you with approximately 500 Coin for every 10 minutes of game length, up to 30 minutes."—In-game description
Maple Festival is a Big Button technology in Age of Empires III: The WarChiefs that is unique to the Iroquois and can be researched at the Plantation. Once researched, it ships 500 coin for every 10 minutes the game has passed, up to 30 minutes (for a total of 1,500 coin).
Note that if Maple Festival is researched before the game time reaches 10 minutes, no resources will be shipped, wasting the cost.
