Platinum coins are the highest currency in Terraria, a popular sandbox game with elements of exploration, crafting, and combat. Platinum coins can be used to buy items from NPCs, craft powerful weapons and armor, and even create a trillion-dollar coin for fun. But how can you get unlimited platinum coins without cheating or hacking? Here are some tips and tricks to help you out.

If you play Terraria in Journey Mode, you can access a feature called Research and Duplication that allows you to create infinite copies of any item you have researched. To research an item, you need to collect a certain amount of it and then drag it into the research menu. Once you have researched an item, you can duplicate it as many times as you want by dragging it from the duplication menu.

One way to get unlimited platinum coins is to research and duplicate gold or silver ore, bars, or coins. According to Screen Rant, you need to collect 100 pieces of gold or silver ore and then smelt them into bars using a furnace. Then, you need to research and duplicate as many bars as you can and sell them to a shopkeeper for coins. Alternatively, you can research and duplicate 100 gold coins and then craft them into platinum coins using the crafting menu. You can then research and duplicate the platinum coins and enjoy your unlimited wealth.

If you play Terraria in any other mode than Journey Mode, you can still get unlimited platinum coins by using a combination of two rare items: the Lucky Coin and the Slime Staff. The Lucky Coin is a hardmode accessory that drops from pirate enemies during the Pirate Invasion event. It has a 1/4000 chance of dropping from any pirate enemy, except for the Flying Dutchman. The Lucky Coin causes enemies to drop more coins when damaged.

The Slime Staff is a pre-hardmode summon weapon that summons a baby slime minion to fight for you. It has a 1/10000 chance of dropping from any slime enemy, except for the King Slime and slimed zombies. The Slime Staff is the weakest summon weapon in the game, but it has a very high attack speed and can hit multiple enemies at once.

The trick is to equip the Lucky Coin and summon the baby slime minion near an enemy spawner, such as a statue or a meteorite. The baby slime will constantly damage the enemies, causing them to drop more coins thanks to the Lucky Coin. You can then collect the coins or use a coin gun to shoot them at other enemies for more damage. This method can generate a lot of platinum coins in a short time, but it requires a lot of luck and patience to get the Lucky Coin and the Slime Staff.

Platinum coins are very useful and valuable in Terraria, but they are not easy to come by. However, with some creativity and ingenuity, you can find ways to get unlimited platinum coins without cheating or hacking. Whether you use Research and Duplication in Journey Mode or Lucky Coin and Slime Staff in other modes, you can enjoy having infinite money to spend on whatever you want in Terraria.
