Reprinted in 1977 by Obol International as Imperial Persian Coinage . In the following illustrations, the areas in black are incuse, that is, they descend below the surface of the metal. Design areas in white are to be inderstood as standing in relief against the surface of the metal which has been depressed around them. Some marks are entirely incuse, and a few are in relief against a non-descript depression of the metal around them.
Most marks consist of a combination of incuse and relief design elements.
The marks have not been drawn to any common scale.
