Obol

Methylion was a small Thessalian community whose independent coinage output was brief and geographically confined — the BCD collection remains the primary reference point precisely because so few examples have surfaced outside major specialist sales. The obol denomination in Thessaly during this period was functional small change, used in local markets rather than interstate commerce, which means most examples saw hard use before disappearing from the record entirely.

The BCD Thessaly I sale in 2006 brought sustained scholarly attention to exactly these minor Thessalian mints, several of which had been lumped under uncertain attributions for decades prior.
