Tetartemorion

Delphi's autonomous silver coinage is closely tied to the sanctuary's administrative role rather than any civic minting tradition — the issues served practical needs of the festival economy surrounding the Pythian Games and the constant traffic of pilgrims, theorodokoi, and merchants passing through the sanctuary. At this fractional weight, the tetartemorion functioned at the lowest viable denomination of Greek silver coinage, useful for small transactions that even an obol could not accommodate.

The BCD collection reference places this among material assembled by a single specialist over decades; BCD Lokris 369 reflects the geographic cataloging convention grouping Phokian and Delphic issues together under broader Central Greek regional headings.
