I'm curious about zinc coins. I want to know what they are, their properties, uses, and maybe even their history. Are they still in circulation or more of a collector's item?
This new composition was composed of 95% zinc, a significant increase from the 5% zinc used before 1981. 5. Coin collectors have coined the term "zinc CORE alloy" to describe this new composition.

The introduction of the clad alloy necessitated the development of new technologies for its fabrication and coining.
