You most likely have an Iran 100 dinars, Dennis. It is a pretty coin, isn't it? The one in our picture has exceptional eye appeal. Nice!
These coins bear Hijri (Islamic) dates. AH1318 to AH1326 (Hijri) corresponds to 1900AD to 1911AD (Gregorian).
Values are still quite low, although collectors will pay premiums for nice-looking specimens. Here is what the catalogs say:
worn: $5 US dollars approximate catalog value
average circulated: $10
well preserved: $16
fully uncirculated: $36
Dates AH1318, AH1319, and AH1326 are somewhat less common and command slightly higher prices.
