Platinum-190 – $32 Billion/ Kg

As the name suggests, Platinum-190 is linked to nuclear physics as it is used in various levels of research. As we all know, anything to do with nuclear stuff doesn’t come cheap, and this isotope is no different.

Platinum-190 costs $32 billion per kilogram, so it is safe to say this is not your usual frog dissection experiment back in high school. Whatever these physicists are investigating must be really important to be trusted with such an asset. On the other hand, we wonder if the deposits of this commodity are guarded more securely than Fort Knoxx. 32 billion is more zeros than you can ever need in your account.
