The numismatic history praises a few prominent examples that might have influenced the whole sphere up to these days of digital (non-classical, for sure) supremacy. Back then, in Ancient Greece, there appeared tetradrachms, i.e., coins that managed to become a “standard of Antiquity” and a foundation for other trading objects to emerge.
The Greek silver tetradrachm coin itself is a symbol of Ancient Greece, though its influence expanded on the surrounding areas as well. So, what is a tetradrachm, and how valuable might this old coin be today? Let us briefly cover the main characteristics of this significant historical attribute and learn more about the peculiar representatives of this coin group.
A Bit of its History: The Origin of the Tetradrachm
In essence, a tetradrachm is one of the most iconic and prominent examples of coins that appeared and developed during the renaissance of the Classical Age. The earliest instance of a silver tetradrachm coin dates back to the 6th century BCE, when Greek states required a united, more generalized currency system to make commercial relations more stable and easier to maintain.
Affected by the earlier precious-metal coinage systems (i.e., in Lydia and Persia), there appeared the tetradrachm which literally means “four drachmas” with the latter representing another (yet small) currency unit in Ancient Greece. The first coin was presumably minted in Athens with an owl, i.e., the symbol of wisdom and Athena, on it. Hence, this was originally known as Athenian owl tetradrachm, an indicative historical element of the state and the whole region.
Initially, since a tetradrachm coin value was higher than that of an ordinary tetradrachm, it became a widely used currency in terms of large-scale trading on the territories subject to Hellenistic influence. These numismatic creations were indeed valuable (which is obvious), though their aesthetic appeal was also an indispensable part of the coins. This is why each state strived to produce the most exquisite tetradrachm with prominent illustrations and hidden meaning inside.
Characteristics of Tetradrachms
Although the nature of tetradrachm could have been different due to the various places of origin and cultural backgrounds, these represented a golden (silver, in fact) standard of coin mintage in Ancient Greece. They all were to be minted following the same patterns so as to establish a unified system in the end. Here is a generalized description of this type (mainly, on the example of the Athenian Tetradrachm):
Weight | 17.2 grams (as a standard) |
Composition | 24 to 27 mm |
Edge | Smooth |
Mintmark | The early instances did not have any mintmarks, though those of a later origin might incorporate symbols/letters appealing to the region of mintage, authorities, etc. |
Composition | Pure silver (95-98%) |
Obverse | Each state featured different designs. The Athenian Tetradrachm was known for the profile of Athena in a helmet (a symbol and a protector of the city). |
Reverse | Another side of the coin should have displayed something associated with the contents of the obverse (e.g., a symbol, deity, or a ruler). For instance, the Athenian Tetradrachm showcased an owl, an olive branch, and an inscription “AOE”, which means “of the Athenians”. |
