A double stater coin (an ancient Greek or Near Eastern coin worth twice a stater).
From Greek 'di-' (two) + 'stater' (a standard coin unit), literally meaning a coin worth two staters or roughly two drachmas.
Ancient distaters are prized by collectors because they're rare evidence of how different Greek city-states valued their currencies—holding one connects you to commerce from 2,500 years ago.
