Historical Context: This 20 Sen Pattern coin emerges from the pivotal Meiji Restoration period (1868-1912) in Japan, an era defined by Emperor Meiji's rapid modernization and Westernization. The adoption of a decimal currency system, replacing the complex Edo-period coinage, was a cornerstone of these reforms. This pattern piece represents an experimental phase in the establishment of the yen/sen/rin system, demonstrating the Mint's trials with specific denominations and alloys, such as billon, before finalizing the circulating coinage. Its existence underscores the significant effort to create a standardized, modern currency for a newly unified and internationally engaged Japan.
Artistry: The design of this 20 Sen Pattern reflects the nascent fusion of traditional Japanese symbolism with Western medallic art principles prevalent in early Meiji coinage. While a specific engraver is not noted, early designs were often influenced by foreign experts or Japanese artisans trained in European techniques. The obverse typically features the majestic imperial dragon, a potent symbol of the Emperor's authority and national power. The reverse commonly displays the Kiku-no-Gomon (Chrysanthemum Seal), the imperial crest, often surrounded by a sunburst and the denomination in Kanji, embodying a blend of ancient heritage and modern numismatic clarity.
Technical/Grading: Struck in billon (.460 silver), this pattern coin measures 18.3 mm and weighs 2.17 grams. As a pattern, it likely exhibits an exceptionally sharp strike, often superior to regular circulating issues, as it served as a prototype for evaluation. Key high-points for grading would include the intricate scales, whiskers, and claws of the obverse dragon, which should show full detail. On the reverse, the central petals of the chrysanthemum and the radial lines of the sunburst would be critical areas. The billon alloy, with its lower silver content (46%), may present a distinct luster and strike characteristic compared to higher fineness silver issues, yet its detail should be crisp.
