Provenance: Grand Duke Alexandre Michaïlovitch Collection (1866-1933), Naville IV (17-19 June 1922), 705. Naville X (15 June 1925), 650. The Naville IV sale is renowned for including the collection of Grand Duke Alexander Mikhailovich. According to E. V. Zakharov, the portion of his collection sold at Naville consisted exclusively of gold coins from Kyzikos (Nos. 691–781). This coin is therefore one of the few for which we can be certain that it belonged to this famous collection.
