Nepal 4 Paisa 1955: "Bullet Paisa". These coins were minted with planchets made from .303 Lee-Enfield cartridges used by Gurkha soldiers during World War II.
Amazing!

Not really a "coin", but interesting unusual and rare (in terms of refined availability) metal . Scandium metal.

You know, if material collecting ever takes off, countries might end up doing some element series coins. Scandium is one of the few feasible metals that hasn't been tried yet.

Oh yes. Fred Zinkann made a number of interesting fantasy coins c. 1989. Some include metals that are otherwise not seen anywhere else in numismatics, such as rhenium and hafnium.

This coin was struck in Rhenium, Zirconium, Cobalt, Hafnium, and Tantalum

https://en.numista.com/catalogue/se....php?id=3631

Mine weights 6.6 g (close to the stated 6.8 g in the link), pretty much conforming it is the tantalum version (I purchased it as tantalum). Tantalum had a series of 100, the rest 10 or less.
