What is the most expensive item in the world?

The most expensive item in the world is Antimatter
Where was the cost of producing one gram of which 62.5 trillion dollars
(Trillion = thousand million million billion =)
Anti article is the opposite of material which does not exist in our world is near
But in different places in the universe
Every body there antibody have the same mass
All other characteristics are similar
As they are all anti-shipping
For example, a positive charge of the proton, while the anti-proton has a negative charge
