Currency
Obols were used from early times. According to Plutarch they were originally spits of copper or bronze traded by weight, while six obols make a drachma or a handful, since that was as many as the hand could grasp. Heraklides of Pontus in his work on "Etymologies" mentions the obols of Heraion and derives the origin of obolos from obelos. This is confirmed by the historian Ephorus on his work On Inventions. Excavations at Argos discovered several dozen of these early obols, dated well before 800 BC; they are now displayed at the Numismatic Museum of Athens. Archaeologists today describe the iron spits as "utensil-money" since excavated hoards indicate that during the Late Geometric period they were exchanged in handfuls (drachmae) of six spits, they were not used for manufacturing artifacts as metallurgical analyses suggest, but they were most likely used as token-money. Plutarch states the Spartans had an iron obol of four coppers. They retained the cumbersome and impractical bars rather than proper coins to discourage the pursuit of wealth.

In Classical Athens, obols were traded as silver coins. Six obols made up the drachma. There were also coins worth two obols ("diobol") and three obols ("triobol"). By the fifth century BCE, variations on obols expanded to include coins worth one and one-half ("trihemiobol") obols and half obols ("hemiobol"). The fourth century BCE diversified further with some minted obols worth as little as one-eighth obol, equivalent to a single copper. Each obol was divisible into eight "coppers" (χαλκοί, khalkoí). In some other cities the obol was instead divided into twelve coppers. During this era, an obol purchased a kantharos and chous (3 liters or 6 pints) of wine. Three obols was a standard rate for prostitutes. In the fourth century BCE, bronze obols were first minted, which were generally larger due to bronze being a less precious metal than silver, thus needing a larger amount to produce an equivalent coin. This larger size made bronze coins fairly popular, as their small, silver predecessors were much easier to lose track of.

Obols had a variety of designs stamped into them based on the region in which they were produced. Athenian obols were typically emblazoned with the face of Athena on one side, and an owl on the reverse. Other regions in Greece had various designs, but the Athenian design was popular enough that the majority of obols discovered by archaeologists today bear the owl design. Diobols and triobols were differentiated from standard obols through slight variations to the owl design, changing the way the bird faced and how its wings were positioned for easily identifiable currency.

Weight
The obol or obolus was also a measurement of Greek, Roman, and apothecaries' weight.

In ancient Greece, it was generally reckoned as 1⁄6 drachma ( c. 0.72 grams (0.025 oz)). Under Roman rule, it was defined as 1⁄48 of a Roman ounce or about 0.57 grams (0.020 oz). The apothecaries' system also reckoned the obol or obolus as 1⁄48 ounce or 1⁄2 scruple. While 0.72 grams was the weight of a standard Greek obol, the actual amount of silver that went into making the currency could vary from region to region. Obols in Athens were typically near the 0.72 gram standard, while Corinth was documented having 0.42 gram obols.
