# What are the three precious metals?

But there a lot more metals with intrinsic monetary value than these three. Platinum, iridium, rhodium, and many more more metals have substantial value per $\text{gram}$ or per $\text{troy ounce}$ (whatever these are - traditionally troy ounces were used to express masses of precious metals). Trade and speculation in precious metals is extensive, and you can find the prices per gram or per ounce on the web.
