The National Bank of Greece turned to the American Bank Note Company in New York for this issue at a time when no Greek printer could produce work of comparable security or finesse. ABNC dominated the market for government securities and banknotes across multiple continents in this period, and Greek authorities had used them for earlier issues as well — a relationship driven by both quality and the absence of a domestic alternative.

The 1867–68 date range suggests production across two fiscal years, though individual note dates within that window vary. ABNC's intaglio printing on issues of this age is prone to surface oxidation along fold lines, a known vulnerability of the ink compounds used in their mid-Victorian output.
