The max total for collecting include all attractions enchantment levels. But character tasks will only drop for character needs and all the next available attraction level. After that, only chest and attractions will drop additional common tokens until hitting test max total.
For example, all the duck tales characters I have are maxed out and as a result would no longer drop common tokens. Then not long ago, I got the money bin from a chest. So at that point the Nephews resumed dropping common token until I reach enough for level 1 enchanting. After that, attraction and chests continued to drop #1 Dime tokens again until I hit 150. Enchantment requirements are:
lvl 1 - 10
lvl 2 - 20
lvl 3 - 30
lvl 4 - 40
lvl 5 - 50
Which add up to that same 150. I COULD (and likely will) add up all the levels I have remaining for each family of attractions but that sounds super tedious so I’m looking for shortcuts to avoid it.
I’m down to just Frozen, Coco, Star Wars, Lady & The Tramp, Onward and now Pocahontas common token chest drops. Though clearly those last 3 will be with me for a long whole to come.
