Bonus question what is the densist also?

I know platinum is the most expensive metal, but is isnt the most expensive substance on the planet, it is also around 22ton / sq m there is something denser.

Forgot about fish and chips at the little chef. Wow, that will take some beating.

the answer to both questions would be in the transuranic elements.
Plutonium would probably be the densest that you could use
one of the exotic short lived transuranics would probably be the most expensive
just remembered this gem:
A major research institution has recently announced the discovery of the heaviest chemical element yet known to science.
The new element has been named Governmentium. Governmentium has 1 neutron, 12 assistant neutrons, 75 deputy neutrons, and 224 assistant deputy neutrons, giving it an atomic mass of 312.
These 312 particles are held together by forces called morons, which are surrounded by vast quantities of lepton-like particles called peons.
Since governmentium has no electrons, it is inert. However, it can be detected as it impedes every reaction with which it comes into contact. A minute amount of governmentium causes one reaction to take over 4 days to complete when it would normally take less than a second.
Governmentium has a normal half-life of 2 to 4 years; it does not decay, but instead undergoes a reorganization in which a portion of the assistant neutrons and deputy neutrons exchange places.
In fact, governmentium mass will actually increase over time, since each reorganization causes some morons to become neutrons, forming isodopes.
This characteristic of moron-promotion leads some scientists to speculate that governmentium is formed whenever morons reach a certain quantity in concentration. This hypothetical quantity is referred to as Critical Morass.

It's difficult to place a monetary value on some of the rarer elements; their half lifes make trading uneasy.
I'd suggest that anti-matter would be the single most expensive "substance" in existence if it was readily traded (I have heard estimations that a gram of antiprotons would cost in the order of several hundred billion dollars). Weight-for-weight, I doubt any single substance matches this.

Saffron, gram for gram much more expensive than platinum.
It is not a herb..it is made from the stigmas of flowers like the crocus.
Densest is the metal Osmium Os.

The most expensive element is tritium, although some pharmaceutical compounds are probably costlier. The densest element is osmium.

Seriously, I think it's saffron, the herb

I'm told PRINTER INK is one of the most expensive
