I agree that they are not particularly lovely. In response to the question about billon, here is what Wikipedia says: Quote: Billon ... is an alloy of a precious metal (most commonly silver, but also mercury) with a majority base metal content (such as copper). The use of billon coins dates from ancient Greece and continued through the Middle Ages. During the 6th and 5th centuries BC, some cities on Lesbos Island used coins made of 60% copper and 40% silver. In both ancient times and the Middle Ages, leaner mixtures were adopted, with less than 2% silver content.

Quote: most commonly silver, but also mercury Can anyone explain to me either how a coin can be made of mercury or how mercury is a precious metal?

I do see this: Beginning in 2006, Dave Hamric (Metallium) [5] has been attempting to strike "coins" (technically tokens or medals, about the size of a US cent) of every possible chemical element. To date he has struck tokens of the following elements, Mercury (sealed in resin cast)

they may be solid but are they stable enough under normal atmospheric conditions to be used for coinage? and not be poisonous?

Do you have a silver tooth? It's made of silver amalgam, which is a Ag/Hg alloy.

Here's another Notgeld piece, this one from Mainz   I guess you would consider composition to be brass, postage stamp, celluloid and whatever is in back of the stamp!

Finally found one of these for a reasonable price:  Clay sen issued by a private firm for a few weeks or days at the final moments of WWII.
