Something that just popped out of my mind while I was typing out for a reply in one of the forum topics.

What kind of exotic metals / alloys do you have for coins? The only exotic one that I have ever seen is clay, porcelain and fibreglass coins, well technically they aren't metal... Or I guess mine is platinum and palladium, but they aren't really THAT exotic... compared to the other rare metals out there.

Look at the bottom page <- Interesting clay and porcelain coins.

But yes, of course there are some coins that aren't struck in certain type of metals, such as nobium and titanium, although they both do exist If I am not wrong, I think Austria has released a coin that's purely titanium, or probably one of the British Islands, (I never get them right...). The nobium coin was released as a bimetal, produced by a Swiss mint... hopefully I am not horribly off...

Here is an interesting list of metals ever used in coins, although it might be slightly outdated, it's highly interesting.

Metals used in coinage

The weirdest ones I have are iron. Nothing real spectacular.

Plus the rust factor... lovely.

I've got nothing special.

Gold, Zinc and (stainless) steel are the most rare metals in my collection, as well as pure copper.


Tiff, didn't you have a coin with ceramic inlay, that Polish one?

Yes that's true.

Ah yes, that Polish coin Tiffy?

Currently only ones been in this collection are;

Gold,
Silver,
Copper,
Bronze,
Cupro-Nickel,
Tin,
Zinc,
Aluminum,
Steel (plated with either Zinc or Copper),
Nickel Brass,
and some Brass gaming tokens.

I think that's them all...

Austria has indeed issued some silver/titanium and silver/niobium coins (bimetallic and bi-color). Latvia issued a similar Ag/Nb piece. These were all made by the Austrian Mint. There may well be other countries that also made such coins ...
