Mexico 1884 – Fábrica de Tunal 1 Peso (Pick Unlisted, ABNC)

One of the most sophisticated corporate issues produced in northern Mexico during the Porfiriato modernization period, this fully issued and serialed 1 Peso note from La Fábrica de Tunal represents a hybrid monetary instrument that straddled formal banknote design and private scrip functionality. Unlike the majority of locally lithographed corporate payroll chits of the 1880s, this piece was engraved and printed by the American Bank Note Company in New York-an extremely rare choice for a non-bank issuer and clear evidence of the company's scale and financial ambition.

New Zealand 1924-1925 - Bank of New Zealand 10 Shillings with SPECIMEN Perforation Front Proof (Pick S231p1)

The intact margins and deep relief impression make this piece an ideal teaching reference for plate-making and tint-stone layering techniques used by BWC during the interwar modernization of New Zealand’s private-issue currency. It stands as an educational artifact bridging colonial design tradition and the technical precision that would define later Reserve Bank series. Read more →

Argentina 1871 - Banco de Londres y Rio de la Plata 10 Pesos Rosario No. 000001 Specimen (Pick Unlisted)

It demonstrates how provincial Argentine banks adopted London engraving precision while applying local iconography tied to regional progress. Read more →

Argentina 1884 - El Banco del Chaco 1 Peso Moneda Nacional Oro Serial 15849 (Pick S1566)

These notes circulated briefly across the northern frontier, a region opened by British-funded rail and river trade. Each surviving piece testifies to the reach of foreign engravers in shaping Argentina’s economic imagery. Read more →

Graded PMG 64 Choice Uncirculated and standing at the top of the population report, this example ranks as the finest known for the type.

Argentina 1866 - Banco de Londres y Rio de la Plata 1 Real Rosario Type A with Printed Signature Issued Note (PS1731, Bauman SFE 70)
