Watch List notes:

YUGOSLAVIA: 4 Dukata (1931) in gold (0,986). Obv: Conjoined busts of royal couple. Rev: Crowned double eagle with shield on breast. In our opinion it is "birds" countermark despite the fact that NGC certified it as "swords" countermark. Inside slab by NGC "UNC DETAILS - OBV CLEANED". (KM 14.1).
