YUGOSLAVIA: Alexander I, 1921-1934, AV dukat, 1932, KM-12.2, with wheat and "I 1" countermark, PCGS graded MS62. The countermark applied on this coin is now regarded as marking different sequences of issue, with the latest probably being a wheat grain ear mark and letter 'I' and numeral '1'. The 'I' reflects the quality of the gold, and the '1' indicates it was validated at Belgrade. This newer research is in the article Yugoslav Countermarks on Austro-Hungarian Gold Coins by Aleksander N. Brzic, from the American Journal of Numismatics.
