The first coins were typically made from electrum, a natural alloy of gold and silver. This choice of material was due to its availability and the inherent value of gold and silver, which made the coins widely accepted in trade. Over time, other metals such as copper and bronze were also used as coinage materials.
While the person is not known, coinage was used by the Phoenicians. The first coins appeared in the Mediterranean Sea area about 1500 BC.

A coin die is a tool which is used to male coins and structural materials. Types of dies have been in existence since the Middle Ages.
To bring a large amount of coins to the bank, first, sort and count the coins at home using coin wrappers or sorting trays to make the process easier. Once sorted, roll the coins into wrappers according to denomination, as most banks prefer coins to be organized this way. Finally, take the wrapped coins to the bank, and if needed, check with your bank about their specific policies for coin deposits.
Banks use machines that separate coins by size and weight. Depending on the country, they can be purely mechanical, electronic, or more likely a combination of the two methods. If each denomination is a different size, the coins may be put through a mechanical sorter that sends them over a series of hoppers with holes that let the smallest coins drop first, then the next-smallest, and so on. Mechanical sorters may also have magnets or electronic sensors to weed out slugs and foreign coins that match in size but not metallic properties. If some denominations are the same diameter but made of different metals or have different thicknesses, a sorter could separate coins using weight sensors and/or electronic scanners, somewhat like the mechanisms used in vending machines.
Coins have been used for thousands of years. The first British coins that are still currently in circulation are the 1 Penny and 2 Pence coins.
