Issue: This is from the first metal issues of the riyal during the reign of King Khalid, may God have mercy on him. • King Khalid's issues are less common than the coins of the kings after him (Fahd and Abdullah), so they are considered desirable for collectors, especially if they are in excellent or uncirculated condition. • The 100 halalas metal coin began to appear with the issues of the Saudi Monetary Agency (SAMA) in the seventies AD (1392 AH and onwards), and it had more than one design over the years.
