Money is essential for buying Poké Balls, Potions, and TMs. One of the best ways to earn money is by battling trainers repeatedly using the Vs. Seeker, an item obtained on Route 3. Equip an Amulet Coin (found in the Celadon City Mansion) to one of your active Pokémon to double your prize money from battles. Selling Nuggets, Big Pearls, and other valuable items found throughout the game is also a quick way to accumulate cash. check trash cans for hidden items!
While the Vs. Seeker provides consistent income in FireRed, the Pokémon Ranger spin-off replaces traditional prize money rewards with a mission-based experience system focused on capture streaks.
While Pokemon GO focuses on earning PokéCoins through gym defense, FireRed players must instead rely on the Vs. Seeker and Amulet Coin to actively farm currency from trainers.
