3 000 000 Lira Galata Tower

Turkey's late-1990s commemorative silver program coincided with chronic hyperinflation that had rendered everyday coinage nearly worthless — by 1998, the Turkish lira had lost so much purchasing power that a face value of three million lira on a silver coin was, in practical terms, a rounding error against the metal's own worth. The denomination was ceremonial arithmetic, not monetary policy.

The Galata Tower itself predates Ottoman Istanbul: the Genoese rebuilt it in 1348 as the Christea Turris, a watchtower over their trading colony in Pera. It passed to Ottoman hands in 1453.
