Answer:
Zinc does not contain a coinage metal.
Explanation:
The metals used for coins, copper, silver, and gold, are naturally occurring (like the gold nugget in this image), therefore it is likely that they were the first metals that prehistoric humans used.
Examples include ornamental gold objects from the late Stone Age and gold Egyptian coins that are more than 5000 years old. Objects made of copper date back to around 5000 BC, making it almost as old.
Before 3000 BC, bronze—an alloy of copper and tin that is tougher than either of its component metals—was utilised, ushering in the Bronze Age.
Silver deposits are significantly less frequent than gold or copper deposits, yet by 3000 BC, techniques for extracting silver from its ores had been discovered, allowing silver coinage to be widely used in ancient times.
