⅕ Toman - Mozaffar ad-Din Qajar Mule/Overstruck - Tehran

A mule produced at the Tehran mint combining dies from two consecutive Mozaffar ad-Din Shah issues — KM#923 and KM#924 — likely the result of a die changeover where an exhausted engraver or distracted mint official paired mismatched obverse and reverse without detection. The late Qajar mint at Tehran was not a rigorous operation; quality controls were inconsistent, and such anomalies slipped through more often than the dynasty's administrators would have preferred.

At under two-thirds of a gram, these fractional gold pieces were struck in small quantities to begin with, making mule survivors genuinely uncommon.
