You get the more coins from more advanced islands and stages.

Level your fighters using frogs, and avoid using other fighters as level up material after the first levels as it gets extremely expensive.

Using monsters of the same color as the one you want to level increases the exp by 50%.

When you level up a fighter, make sure you use 5 monsters in the level up process. If you dont have 5 then wait until you do. That saves a lot of coins.
