The Amulet Coin doubles the amount ofprize money received after battle if the holder takes part in the battle. It also doubles the number of coins picked up fromPay Day,G-Max Gold Rush, andMake It Rain. InPokémon Colosseum's Story Mode andPokémon XD's colosseums, this bonus can be applied to the prize money earned after clearing a set.
InPokémon Ruby and Sapphire only, due toa minor glitch, when collecting money dropped by Pay Day, the amount displayed will be incorrect if it was boosted by an Amulet Coin (the correct amount will still be obtained).
Once the Pokémon has participated in battle while holding it, it takes effect; it is unaffected byKlutz and takes effect even if the holding Pokémon faints or the Amulet Coin is removed or negated.
InPokémon: Magikarp Jump, the Amulet Coin is a Friendship Item that is obtained as a prize for beating the Great League. It summonsMeowth as a helper Pokémon.
An Amulet Coin appeared inCapacia Island UFO!, where it was found byAsh. Later, when he andTeam Rocket entered a UFO belonging to a group ofBeheeyem, the Beheeyem told them that they lost an item looking like the Amulet Coin that was a vital part in getting the UFO to fly. Ash gave them the Amulet Coin he found, but it was not the right item. Instead, the Beheeyem sought a similar-looking item, which had been found byJames earlier on.
Amulet Coin was introduced as aPokémon Tool card in thePokémon Trading Card Game during the English Diamond & Pearl Series (the Japanese DP Era) in theGreat Encounters expansion. When a player attaches thisTrainer card to their Active Pokémon, they can draw an additional card at the end of their turn.
