Platinum Ore

Platinum Ore is an early game ore which spawns in the Underground and Cavern biomes, as well as on Floating Islands. Its primary use is to make Platinum Bars, which can be used to make the fourth tier of equipment, as well as crowns, thrones, and several other items. The equivalent of Platinum Ore is Gold Ore, which will sometimes replace Gold on a world. Platinum is the superior counterpart to gold.

Trivia

 * Even though gold and platinum bars and ores are of equal value, platinum coins are worth 100 gold coins. However this may be a reference to the fact that in real life platinum is worth more, and also because the coin came first.
