10 Lira crescent to left

Turkey's aluminum coinage of this period was produced under the shadow of the September 1980 military coup, which brought the National Security Council to power and restructured virtually every arm of the state — the mint included. The "crescent to left" designation distinguishes this from a parallel die variety where the crescent on the reverse faces right; both exist for this year, making die attribution genuinely consequential for type collectors rather than a footnote.
