100 Mon "Tenpōtsūhō" - Japan

A fine example of modern numismatic art, the 100 Mon "Tenpōtsūhō" - Japan from Japan (1835–1870), denomination 100 Mon, showcases the design achievements of its era. From the great mints of Philadelphia, London, Paris, and Vienna, modern coinage elevated everyday currency into miniature works of art, capturing likenesses of monarchs, allegorical figures, and national symbols. A product of the modern era, this coin reflects industrialization, nation-building, and the standardization of coinage systems that characterized the nineteenth and early twentieth centuries. The introduction of steam-powered presses transformed coin production from an artisanal craft into an industrial process, enabling mints to strike millions of identical pieces per year. Modern coins are distinguished by their high relief designs, standardized alloys, and consistent weights — physical manifestations of the new monetary orthodoxy. Struck in bronze, this coin belongs to the workhorse category of historical coinage. Bronze coins circulated in enormous quantities, passing through countless hands in markets, taverns, and counting houses. Their survival in any condition is a testament to the durability of the alloy, while examples in superior grades are prizes for the discriminating collector. For the serious numismatist, acquiring this coin in the finest available grade is the ideal strategy. Professional certification from NGC or PCGS not only authenticates the piece but encapsulates it in tamper-evident holders that protect against accidental handling damage. The long-term value proposition of well-graded, original-surface examples of numismatic rarities has been demonstrated repeatedly in the major auction houses of New York, London, and Hong Kong.
