Hey Sag thanks for responding. The two larger coins appear to have the same date. Looks like 1370. Ill check the others later.
Thanks don. Cool to know. That's an odd percentage isn't it? Not quite sterling.
Odd, indeed.
To figure the basic silver value, look up the price of silver at kitco.com and multiply it by the number of troy ounces of silver in your coin, as follows:
1/4 RIYAL, 19 mm diameter, 0.086 troy ounces silver
1/2 RIYAL, 25 mm diameter, 0.175 troy ounces silver
1 RIYAL, 31 mm diameter, 0.342 troy ounces silver
