Non-Metallic Coins

I recently acquired a 1 fen Manchukuo coin, it is made from red fibre. I was wondering if anyone is aware of any other examples of non-metallic circulating coins.
I know that the Japanese issued a clay coin towards the end of WWII, are there any other examples?

German notgeld. - a lot of different materials, notably ceramic.
Spanish ciwil war coinage - carboard.
Transnistria - plastic.

All I remember now.

Thanks for letting me know. I can't imagine that there are many of those Spanish cardboard coins left.

Most of this coin is metal, but a part of it is not
Issued today. The hell is going on here in Germany. This thing was hyped a bit in newspapers in in TV and so on.

My bank told me, they will not get them.
The Bundesbank gives only one coin per person.
The people on ebay are running crazy.

And all this because of a piece of plastic as part of a coin.

​That is one ugly coin. And it's not even silver!

Here is a Depression Era scrip from Willapa Harbor Washington. This one is from the first series issued, and it is printed on a thin Cedar sheet. They are quite fragile, and are scarce in good condition. The second series issued was printed on laminated paper.

During Mexican revolution some towns used cardboard coins, even banknotes of 1 cent(avo)

Funny you should ask, I just purchased this set of plastic coins from Transnistria:

Here are German porcelain and wood:

The famous Portugal Gaia Token, made by porcelain.

Another funny example, in French Colonial / Canadian history: monnaie de carte or cards used as tokens to replace missing coinage.

Thanks for all of the answers. There are much more non-metallic coins than I expected.
