Chakra and a conch shell. The coins indicate that the cult of the Vrsni Viras had spread far from their Mathuran homeland, and that they had retained enough importance to be recognised with royal patronage; further, as the Greek obverse would have been superior to the Brahmi reverse, the coins show that Balarama was considered senior to Vāsudeva, in accordance with the traditional lineage system. The second hoard was found three years later, in the kitchen of the extramural residence. This hoard consisted of 63 silver tetradrachms, of which 49 were Greco-Bactrian; a majority of these were dedicated to Euthydemus I, while the others were dedicated to other kings. The third hoard was found during the winter of 1973–4, by an Afghan farmer near the site, and was quickly sold on the antiquities market in Kabul. Although a large portion of the hoard later passed through New York, where a member of the American Numismatic Society was able to compile an inventory, its integrity had then been lost; some coins had been removed, while others, such as a drachma of Lysias Anicetus, had been added. Only 77 of the 224 legible stray coins were Greco-Bactrian or Indo-Greek; there were also 68 stray Seleucid coins, 62 of which displayed Antiochus I. One series of Bactrian coins from the reign of Antiochus I was stamped with a triangular monogram () during the coining process. At Ai-Khanoum, bricks bearing the same mark were found in the heroön, one of the oldest structures in the city. Therefore, it is considered probable that Ai-Khanoum was the site of the primary Seleucid mint during Antiochus' coregency and early sole reign; an earlier mint, which was most likely located at Bactra but may have been elsewhere, was terminated near-simultaneously after a relatively brief period of operation. Wider influence Some items found at Ai-Khanoum, such as Greek olive oil in the treasury or the Mediterranean plater mouldings on Greco-Bactrian artwork, would suggest the existence of large-scale trading networks, but such findings are few, while the Indian art in the treasury seems to have simply been plunder. Historians have thus concluded that Greco-Bactria was isolated in terms of trade, but had a developed administration with a high level of economic diversity. This administration was passed on to the Yuezhi and Kushan nations, as shown by their use of Greek titles and coinage, and their adaptations of the Hellenistic numerical
