Although the mint attribution is highly uncertain, the presence of the distinctive crab on the reverse could suggest Kos as a possibility for the issuing authority, though a small number of other related issues (Naumann 80, 10; Leu wa15, 563) may indicate a more extensive series from an as yet undetermined mint.
