Question About Unusual Coinage Materials/Post Your Unusual Materials Coins!

The ledergeld is reasonably soft and pliant and can be handled without special concern. Every "currency" made of leather I've seen thus far is made of soft leather. Every coin/token I've seen is hard and dry. (That includes a Juan Sanchez sheep shearing farmers token I got last year.)



Do elaborate. Anything visibly unusual? Even not being money sometimes they might be useful for reference purposes. I recently bought a British advertising token that's apparently made of graphite, mainly for that reason (it's on its way right now). I want to see how it compares to the coal dust notgeld. There are a couple of old graphite medals out for sale at the moment but they're quite expensive.

There's also an advertising(?) token out there right now made of zirconium, but as it doesn't look any different from your generic white metal so I'm passing on that one.

Are you aware of the series of coins struck for Islas Malvinas? The 5 nuevo austral coin is a fantasy coin of the Falkland Islands (Spanish: Islas Malvinas) produced by American artist Fred Zinkann in 2006. The denomination likely references to the austral, the currency of the islands' neighbor and proclaimed owner, Argentina, from 1985 to 1991. The coin was struck in nine metals:

brass, 4.4 grams, mintage 25
cobalt, 3.5 grams, mintage 4
cupronickel, 4.04 grams, mintage 25
gold, 5.80 grams, mintage 3
hafnium, 5.4 grams, mintage 4
silver, 4.04 grams, mintage 25
rhenium, 7.1 grams, mintage 10
tantalum, 6.9 grams, mintage 100
zirconium, 2.5 grams, mintage 12

I sold a tantalum coin last December in my ebay store: https://www.ebay.ca/itm/302579963947

Isla Malvinas: I took a look and it appears that one of the rhenium ones is on ebay at the moment. It seems like the weight is the only real way of telling at the moment.

I'm not a big fan of fantasy issues, and I think the only ones I've intentionally bought are the Crescent Isle ones made of acrylic. Here's one of the set...

They look very nice in bright light.

I have mixed feelings about the price of such a thing. Just checked and the person I bought this from last year nearly doubled his prices.

And speaking of rarer metals, Rwanda issued small nclt coins of iridium, rhodium, and ruthenium a few years ago. It seems their earlier issues which didn't feature all three of them are the only ones readily buyable.

Got my British advertising token, and adding it here for reference purposes.

This is supposedly made of graphite. The thing is, it looks and feels exactly the same as the Conradty coal notgeld. I know it's not exactly a cataclysmic difference between graphite and coal dust, but I do wonder if the 'coal' notgelds are graphite. I did see someone out there describing them as graphite and porcelain.

Here's an interesting one that I came across recently. It's a couple of articles about lava medals, which are commemorative medals that were literally struck out of molten lava at various times when Mount Vesuvius was erupting in Italy. They're not coins but still very interesting in my opinion.

Those lava medals are pretty cool.

@nautilator,




I have no idea, I couldn't find any records of one selling or ever being for sale, just references to them in museums.
