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 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 to all NPCs that drop coins.
Update Info
