This one is new to me…
Turkey, 25 kurus, 1956 (KM #886)
This type of coin was the highest valued coin circulating in Turkey at the time. It was minted between 1948 and 1956, making this a final year specimen. It might be the thinnest coin I’ve seen with edge lettering, which reads “TURKIYE CUMHURIYETI” (Turkish for “Republic of Turkey”). Any monetary value this coin had was destroyed when the Turkish Lira was revalued in 2005, after decades of chronic inflation. Mintage of this coin in 1956 was 14,376,000.
