Coin 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, but would in reality drop that or anything around that amount. The same rule applies with Pinky, being set to drop but dropping that or anything a little over or a little under that. This rule applies with all NPCs that drop coins.
