>platinum was too rare, most civilizations didnt even know of it's existance.
Platinum has an insanely high melting point, too high for primitive civilizations to achieve.
Platinum = 1768C
Silver = 962C
Gold = 1064C
Copper = 1085C
Lead = 327C
Tin = 231C
There were reports that the Conquistadors discovered a grey powder that was left over from the Aztec silver refining process. They couldn't melt the powder, but when added to the metal they used to cast cannons, increased the cannon strength. There are likely some cannons on the bottom of the ocean that may have 25% by weight in platinum
