What Is a Dekadrachm? A Giant Silver Coin of Ancient Greece
Ten Drachms in One Massive Flan. Syracuse, Akragas, and Athens Turned the Largest Common Greek Silver Denomination Into Some of the Greatest Coin Art Ever Made.
What is a dekadrachm? A dekadrachm was an ancient Greek denomination worth ten drachms. Under the Attic weight standard, a full-weight example was roughly 43 grams, though Greek cities used different standards and actual weights vary.
Why Dekadrachms Matter
Dekadrachms are famous because several surviving series combine unusually large flans with exceptional engraving. Syracuse produced the best-known examples, including dies signed by Kimon and Euainetos. Athens and Akragas also issued celebrated dekadrachms, and other authorities produced ten-drachm pieces in different periods and monetary systems.
It is safer not to describe the dekadrachm as the single largest silver coin of the Greek world. Greek and Hellenistic authorities occasionally struck still larger silver denominations. What makes the dekadrachm remarkable is the combination of high value, unusual size, rarity, and, in several series, extraordinary artistry.
Why Were They Struck?
The exact purpose was not identical for every issue, and in some cases remains debated. Scholars have connected particular dekadrachm series with large state expenditures, military payments, commemorative or prestige functions, and exceptional monetary needs. Claims that all dekadrachms were specifically diplomatic gifts or victory commemoratives go beyond the evidence.
How Large Was a Dekadrachm?
On the Attic standard, ten drachms theoretically equaled about 43 grams of silver. Diameter varies by issue and striking technique; many famous examples are roughly in the mid-30-millimeter range. Because monetary standards differed across the Greek world, the name describes value within a system rather than one universal weight.
Famous Dekadrachms
Syracuse: Late fifth- and early fourth-century BC dekadrachms are among the icons of Classical coinage. Their quadriga and Arethusa designs gave engravers unusually broad surfaces for ambitious compositions.
Akragas: The extremely rare Akragas dekadrachm, with its eagle-and-hare imagery, is one of the most celebrated Sicilian coin types.
Athens: Athenian dekadrachms use the familiar Athena-and-owl imagery on a much larger denomination than the ubiquitous tetradrachm.
Athens Silver Tetradrachm, Late Classical Owl (350–294 BC)
The same Athena-and-owl imagery the Athenian dekadrachm carried, in the denomination Athens actually flooded the world with: genuine Classical silver at a fraction of dekadrachm cost.
Were Dekadrachms Everyday Money?
Probably not in the way smaller silver and bronze denominations were. Ten drachms represented a substantial sum, and the rarity and limited production of many series suggest specialized high-value use. That does not mean they were merely ceremonial objects: they were real money, and their precise economic role depended on the issue.
Collecting Dekadrachms
Authentic dekadrachms are generally expensive, and famous Syracusan or Akragantine examples can reach very high prices. Attribution, style, surfaces, centering, provenance, and authenticity all matter. Because valuable Greek silver is heavily counterfeited, provenance and a strong authenticity guarantee are especially important.
Collectors who want the same historical worlds at lower cost can consider tetradrachms, didrachms, drachms, and bronze coins from the same cities.
Hieron II of Syracuse Bronze, King in the Age of Archimedes (275–215 BC)
Silver from the city of Kimon and Euainetos runs to six figures; its bronze does not. Genuine Syracuse under Hieron II, the accessible way into the dekadrachm's home mint.

The Masterpiece Denomination
The dekadrachm shows what Greek mints could do when value, flan size, and engraving talent met. Even if most collectors never own one, the smaller silver and bronze of the same cities carry the same history at a reachable price.
