I will check that site out. I didn't know that about columbium/niobium.  High school chemistry was a long time ago. |

If you're going by availability in nature, then technetium is probably the most precious metal. It has no known stable isotopes, so it is very rare in the wild. If you do ever get your hands on some, sell it quickly and don't put it in your pocket. All forms of it are radioactive, and most of its isotopes have half lives measured in hours.
For all these same reasons, prometium is a close second.

The question is not, "which is rarest?", the question is, "which is most expensive?". As we're all coin collectors here, we all know that rarity alone does not necessarily make something more valuable. There must also be high demand, to complement the low supply, to make something valuable.
There are a great many chemical elements that are scarce, but nearly worthless because nobody wants the stuff. Scandium, for example.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis

Copernicium... newest synthetic metal. Costs a lot to run a collider you know - and that only makes a few atoms. So it would be trillions for an ounce of the stuff. Probably more because it has to all be made before you lose too much to radioactivity (27 second halflife...)

It looks to me like the usual suspects (Gold and Platinum) are the most expensive .999 metals, with either of them being in the #1 spot depending on the time of day lately. I have been interested in buying iridum, rhendium, ruthenium, osmium in coin/blob form from elementsales for some time now (still waiting for them to offer more in coin form before pulling the trigger on an order) and they list:
Ruthenium 1 Toz blob - $240.00 - Purity 99.9%+
Rhendium 1 Toz blob - $410.00 - Purity 99.9%
Osmium 1 Toz blob - $810.00 - Purity 99.9%
Iridium 1 Toz blob - $1340.00 - Purity 99.9%

About 10 15 years ago there was a time when they were using that in some composite ice hockey shafts and baseball bats. I still have a decent amount of that in my garage lol. |

Don't forget Vibranium - the Cap owns all of it  |

I am pretty sure Rhodium is the rarest of the noble metals.

Synthetic metal? I wish they could duplicate gold and silver, that would be great!

I used to think europium was, because I once read that europium was $7,500 a kilogram $7,500 a kilogram = $7.50 per gram or $233.25 per ounce. |

I still have a 1 oz. Rhodium bar. I hope it goes back up to 10K!
