5 Pounds National Theatre

Egypt's National Theatre was founded in 1935, but the commemorative issue marking its anniversary came during a period when Cairo was aggressively using silver coin programs partly as a hard-currency generation mechanism — Egyptian commemoratives of the 1980s were frequently struck for export sale rather than domestic circulation. The .720 fineness is notably lower than the .999 or .925 used by most contemporary commemorative programs, a deliberate cost-reduction choice that kept production viable without abandoning silver entirely.
