I just wanted to say that this is really, really cool! Fantastic idea and I am grateful that you showed off the final product. Fascinating.

Op: Have thought about displaying it at an ANA show? Also, if you want to expand iron to include stainless steel, Brazil had a nice design in the 70's:

 

Nice collection theme!

How about porcelain and electrum?

The former is similar to clay and the electrum is gold-silver alloy, so that may already be satisfied in your collection, depending on how specific you want to be with the alloys / variations. Also, maybe there were gemstone, pearl, textiles (maybe something similar to micarta), and pure enamel used for coinage somewhere, sometime.

And, there's salt paid to ancient Romans but that was raw salt I believe lol.


Pics from the 'net:

Many porcelain examples exist from 1923 Germany in denominated coinage - the one below, however, is a medal.

 

I just finished the set recently so I haven’t really put any thought into displaying it anywhere yet. Also in regards to adding stainless steel, I’m trying to avoid adding alloys unless there it contains a new metal that is not already represented in the set due to the fact that if I add one alloy I would have to add a lot. There were a lot of different alloys used in coins throughout history.

 

Porcelain seems a little too close to the clay sen that I posted in that clay and porcelain are more or less the same material it’s just the manufacturing method that is different, low fire vs. high fire. I’m trying to avoid alloys so electrum is out since gold and silver are already represented.

Something made of gemstone, pearl, textile, and or pure enamel would be great to add but even with all of my research I haven’t come across any coins or tokens that circulated made out of any of those materials. If you know of any please let me know.

 

Did you forget the stone money from Yap in Micronesia? You might be able to buy one from its owner but you'd probably have to leave it in place, as they do.


These aren't coins by your definition but an example of what could be:

Way cool collection! It's so interesting, and it's difficult to come up with a new type of collection, that this was a great idea. You have some really, really interesting pieces.

The only other type I can think of is ceramic. Siamese ceramic gambling tokens were also used as circulating currency from what I understand.

Here are two of mine;

 

I'd say the "ceramic" is just another type of porcelain/clay. Electrum is just a naturally occurring (and variable) alloy of gold and silver which are already on the list.

 

Those are some nice tokens, thanks for sharing but ceramic is a little too close to the clay item that I already have listed in the set for my taste but you are right the Siamese gambling token were used for general circulation until they were outlawed in 1917.

You mentioned interesting pieces in the set. So here’s a little known fun fact for you. The 1942 Lodz 10 pfennig coin in the set was actually made out of the fuselage of a crashed Germany fighter plane that’s why they were made of a magnesium/aluminum alloy.
