Money is the main currency used in PokeMMO. In the official localizations of the Pokémon franchise, money is known as the "Pokémon Dollar" or "PokéDollar" and is denoted by the sign . In PokeMMO, the currency simply uses the $ sign, originally used for the Spanish-American dollar.
Uses of money
Currently, money can be used to purchase good and services from NPCs. All Poké Mart vendors sell goods in exchange for money, as do the vendors in the Celadon Department Store. Money is also used to pay the fee required to access the Safari Zone in Fuschia City.
Future uses of money
Though the 'sell' screen is accessible, the ability to sell goods to Poké Mart is not fully implemented. Similarly, the Trade screen shows an interface for the transference of money between players, but is unfinished and unusable. Once it is implemented, players will be able to purchase Coins for use in the Rocket Game Corner in Celadon City.
Being currently unable to sell items, the only way to raise money available to players is to earn winnings by defeating NPC trainers.
This economic scarcity is the cause of some difficulty for players who quickly exhaust their funds on items. However, there are a number of ways to acquire additional money. In the case of a player having already defeated every NPC trainer in the game, the player can make exceptional use of the VS. Seeker. The VS. Seeker, when used, re-activates all NPC Trainers in the vicinity - they become available to battle again. The VS. Seeker can be used once per day per trainer and is obtained from the woman by the counter in Vermillion City Pokémon Center.
Additionally, a hold item known as the Amulet Coin can be used to increase a players' budget. The Amulet Coin doubles winnings from defeating NPC trainers, as long as the Pokémon holding the Amulet Coin was used in battle. The Amulet Coin is given to the player by one of Professor Oak's Aides - the one located in the upper floor of the Guard House at the north of Cycling Road - after the player has complete data of 40 or more Pokémon in his or her Pokédex.
Finally, the Meowth evolutionary line has a signature move known as Pay Day. When Pay Day is used in battle, the player recieves money equal to five times the Pokémon's level. For example, a level 70 Persian using Pay Day would yield $350 at the end of the battle. This move is also affected by the Amulet Coin - a level 70 Persian using Pay Day would have its level multiplied by ten instead of five, and would yield $700 at the end of the battle.
