Ahmad Shah gold Toman Mule AH 1332 (1913/4) MS62 NGC, Tehran mint, KM1073. A lustrous and well-struck example of this unusual issue, struck with a Toman obverse paired with an unadopted pattern die for a 2 Toman reverse. As it was produced for three years, this type is likely not a pattern but rather careless use of available dies that appeared close enough to the standard Toman reverse for workers with either poor reading skills or a lack of attention to slip by.
