Ancient drachma
In ancient Greece, the drachma (drachmḗ, drakhmέː; pl. drachmae or drachmas) was an ancient currency unit issued by many city-states during a period of ten centuries, from the Archaic period throughout the Classical period, the Hellenistic period up to the Roman period under Greek Imperial Coinage. The ancient drachma originated in the Greece around the 6th century BC. The coin, usually made of silver or sometimes gold had its origins in a bartering system that referred to a drachma as a handful of wooden spits or arrows.
Sterling silver
Sterling silver is an alloy composed by weight of 92.5% silver and 7.5% other metals, usually copper. The sterling silver standard has a minimum millesimal fineness of 925. Fine silver, which is 99.9% pure silver, is relatively soft, so silver is usually alloyed with copper to increase its hardness and strength. Sterling silver is prone to tarnishing, and elements other than copper can be used in alloys to reduce tarnishing, as well as casting porosity and firescale. Such elements include germanium, zinc, platinum, silicon, and boron.
Commemorative coin
A commemorative coin is a coin issued to commemorate some particular event or issue with a distinct design with reference to the occasion on which they were issued. Many coins of this category serve as collector's items only, although some countries also issue commemorative coins for regular circulation.

Mint mark
A mint mark is a letter, symbol or an inscription on a coin indicating the mint where the coin was produced. It should not be confused with a mintmaster mark which is the mark of the mintmaster. Mint marks were first developed to locate a problem. If a coin was underweight, or overweight, the mint mark would immediately tell where the coin was minted, and the problem could be located and fixed. Another problem which could occur would be a dishonest mint official debasing the coin, or putting less precious metal in the coin than specified.
Medal
A medal or medallion is a small portable artistic object, a thin disc, normally of metal, carrying a design, usually on both sides. They typically have a commemorative purpose of some kind, and many are presented as awards. They may be intended to be worn, suspended from clothing or jewellery in some way, although this has not always been the case. They may be struck like a coin by dies or die-cast in a mould. A medal may be awarded to a person or organisation as a form of recognition for sporting, military, scientific, cultural, academic, or various other achievements.
Tetradrachm
The tetradrachm (tetrádrachmon) was a large silver coin that originated in Ancient Greece. It was nominally equivalent to four drachmae. Over time the tetradrachm effectively became the standard coin of the Antiquity, spreading well beyond the borders of the Greek World. As a result, tetradrachms were minted in vast quantities by various polities in many weight and fineness standards, though the Athens-derived Attic standard of about 17.2 grams was the most common.
Federal Reserve Note
Federal Reserve Notes, also United States banknotes, are the currently issued banknotes of the United States dollar. The United States Bureau of Engraving and Printing produces the notes under the authority of the Federal Reserve Act of 1913 and issues them to the Federal Reserve Banks at the discretion of the Board of Governors of the Federal Reserve System. The Reserve Banks then circulate the notes to their member banks, at which point they become liabilities of the Reserve Banks and obligations of the United States.
List of circulating currencies

However, excluding the pegged (fixed exchange rate) currencies, there are only 130 currencies that are independent or pegged to a currency basket.

Sybaris
Sybaris (Σύβαρις; Sibari) was an important city of Magna Graecia. It was situated in modern Calabria, in southern Italy, between two rivers, the Crathis (Crati) and the Sybaris (Coscile). The city was founded in 720 BC by Achaean and Troezenian settlers. Sybaris amassed great wealth thanks to its fertile land and busy port. Its inhabitants became famous among the Greeks for their hedonism, feasts, and excesses, to the extent that "sybarite" and "sybaritic" have become bywords for opulence, luxury, and outrageous pleasure-seeking.
