Although only a small percentage of Greek burials contain coins, among these there are widespread examples of a single coin positioned in the mouth of a skull or with cremation remains. In cremation urns, the coin sometimes adheres to the jawbone of the skull. At Olynthus, 136 coins (mostly bronze, but some silver), were found with burials; in 1932, archaeologists reported that 20 graves had each contained four bronze coins, which they believed were intended for placement in the mouth. A few tombs at Olynthus have contained two coins, but more often a single bronze coin was positioned in the mouth or within the head of the skeleton. In Hellenistic-era tombs at one cemetery in Athens, coins, usually bronze, were found most often in the dead person’s mouth, though sometimes in the hand, loose in the grave, or in a vessel. At Chania, an originally Minoan settlement on Crete, a tomb dating from the second half of the 3rd century BC held a rich variety of grave goods, including fine gold jewelry, a gold tray with the image of a bird, a clay vessel, a bronze mirror, a bronze strigil, and a bronze "Charon coin" depicting Zeus. In excavations of 91 tombs at a cemetery in Amphipolis during the mid- to late 1990s, a majority of the dead were found to have a coin in the mouth. The burials dated from the 4th to the late 2nd century BC. A notable use of a danake occurred in the burial of a woman in 4th-century BC Thessaly, a likely initiate into the Orphic or Dionysiac mysteries. Her religious paraphernalia included gold tablets inscribed with instructions for the afterlife and a terracotta figure of a Bacchic worshipper. Upon her lips was placed a gold danake stamped with the Gorgon’s head. Coins begin to appear with greater frequency in graves during the 3rd century BC, along with gold wreaths and plain unguentaria (small bottles for oil) in place of the earlier lekythoi. Black-figure lekythoi had often depicted Dionysiac scenes; the later white-ground vessels often show Charon, usually with his pole, but rarely (or dubiously) accepting the coin. The Black Sea region has also produced examples of Charon’s obol. At Apollonia Pontica, the custom had been practiced from the mid-4th century BC; in one cemetery, for instance, 17 percent of graves contained small bronze local coins in the mouth or hand of the deceased.
