Notes

Drops

Enemy Coin drops are calculated from set values in the game code, but in-game have an unstated variable factor that is multiplied onto that value every time those coins are dropped. For example; the Dungeon Slime is set to drop 1  50  , but would in reality drop that or anything around that amount. The same rule applies with Pinky, being set to drop 1   but dropping that or anything a little over or a little under that. This rule applies with all NPCs that drop coins.
