Francium is the rarest metal. It is estimated that only 30 grams of it exist in earth's crust. However, most of the artificially created elements on the Periodic Table near the end are equally rare because they only exist for extremely small amounts of time and so they do not exist anywhere in the universe currently.
The rarest metal in the Earth's crust is believed to be rhodium. It is a platinum group metal that is scarce in nature and often found in association with other platinum group metals. Rhodium is primarily sourced as a byproduct of platinum and palladium mining.
Osmium is considered one of the rarest metals on Earth. It is a dense and brittle metal that is mainly used in alloys, electrical contacts, and fountain pen nibs due to its hardness and corrosion resistance.
The second rarest element on Earth is unstable so it does not have a long life (22min.), but uranium is the rarest natural element and is the second heavist natural element. Actually, there are even rarer elements that last for less then fractions of a second. Some are so rare that they haven't even been discovered.
Osmium is one of the rarest elements in the Earth's crust. It is considered a rare precious metal and is often found in association with platinum deposits.
Many isotopes of astatine are considered the rarest naturally occurring elements on Earth. Astatine is highly radioactive and has very short half-lives, making it difficult to study and find in nature.
No, I believe not.
Iridium is the most strongest, rarest, densest, expensive, lightest metal ever known

The rarest, by least made, would have to be the John Deere-Dain, with only a couple known to still be in existence after the scrap metal drives of WWII. For more info on the Dain try the related link...
