"Rhodium is the most expensive metal in the world. Some think platinum is but it is not."
The above answer forgets to look at isotopes, and generalizes metals without taking into account the various rarities occurring within a particular chemical element. All elements, includingRhodium, have isotopes which possess properties valuable to industry, and the rarity of those isotopes increase the value of a metal over and above the most common isotope markets generally quote.
Platinum occurs in stable isotopes 190, 192, 194, 195, 196, and 198. The rarest is isotope 190. PT190 makes up 0.014% of all naturally occurring platinum. Therefore, pure platinum 190 occurs at something around 1 part per 5-5.5 Trillion. This metal is so costly and so rare its value can only be estimated. The only estimate done to date for 1 gram of pure platinum 190 is $32 Million per gram.
For people who want to know how much this is per troy oz. Convert $32,000,000(31.103) = $995,296,000.00 per troy ounce.

Was B29 most expensive project of World War 2?
While the B29 was expensive it cannot even compare to the real most expensive project of World War 2. The Manhattan Project was the most costly project to develop the atom bombs used in World Wa2. This project cost well over 2 Billion Dollars in the 1940s. That would be like a 20 Billion or so dollars today. So the atom bombs each cost slightly under a billion dollars a piece.
