In my opinion the bronze coinage od Celt-Iberia should be described in millimeters, like Roman Colonial coins, and not as denominations as Burgos does. These 2 coins, both called semis, underscore this opinion.

Later Roman Hispania issues may be more consistent in size and weight so that demoninations are appropriately used. My experience in that period is limited.

Tne ancient sity of Ostur, was near Carmona, Spain in the Guadalquivir river valley. The coinage of Ostur is very rare. High grade AEs are exceptional. I have never seen one offered.
