50 Yen in Gold

The Bank of Taiwan, though nominally a commercial institution, functioned as the colonial central bank for Japanese-administered Taiwan and also underwrote much of Japan's financial expansion into southern China and Southeast Asia. Its gold-denominated notes were a deliberate instrument of that regional ambition — payable in gold yen, they were designed to circulate credibly beyond the island itself, facilitating trade across the southern Pacific rim where confidence in paper currency was fragile.

The Bureau of Engraving and Printing in Tokyo produced the series to a high technical standard, consistent with its work on metropolitan Japanese issues of the same period. High-denomination gold notes from this issuer in any grade are rarely encountered today.
