40 Yeni Lira Kızılada Feneri

The Kızılada Lighthouse, located on a small island in the Sea of Marmara near Erdek, was built during the Ottoman period and remains an active navigational aid. Turkey's commemorative silver program in the mid-2000s drew heavily on maritime heritage subjects, partly in response to collector demand for themed issues tied to Anatolian geography.

The "Yeni Lira" designation — new lira — reflects the 2005 redenomination that stripped six zeros from the old Turkish lira, a direct consequence of chronic inflation that had rendered the previous currency nearly unworkable in daily transactions.
