I notice that on this 100 fils coin from Bahrain - https://en.numista.com/catalogue/pieces911.html - the Arabic calendar has been incorrectly translated. It's 1965, not 1966 (as seen in the picture)! The mintage list is locked so I couldn't fix it myself.
yes that happens a lot with translation from georgian to islamic calendar. please have some patience. If you find more of these errors, please list them here in this one thread. thanks for your help
