it is not that the dates were entered incorrectly. Your observations are correct, however.
That is, because automatic translation of islamic date into georgian / christian date is not always
accurate. Please orientate yourself on the islamic date where given. In most cases, arab countries using
islamic dates got a comment besides each mintage year where the correct arab lettering is given to help
you find the correct year of mintage for your coin. Hopefully Xavier will read this comment and correct this
himself - because he's the only to do so. If not - feel free to contact him directly. regards, Makake
