The attribution "uncertain Bactrian city" reflects a genuine unresolved debate in the scholarship — Bactria during this period was nominally under Seleucid control following the partition after Ipsus, but local civic minting persisted in ways that central authority either tolerated or simply could not suppress. Syros 63–64 groups these pieces by die linkage rather than by any secure findspot or mint signature, which is why the issuer remains unresolved.

The date range places production squarely within Antiochus I's eastern campaigns to consolidate inherited Seleucid territory — a period of administrative turbulence that likely accounts for the survival of independent civic coinage this far east.
