Japanese 2 Sen coin from the Meiji era.

Denomination and Era:
This is a 2 sen coin, which was worth one-fiftieth of a Japanese yen (100 sen equaled 1 yen). It was minted during the Meiji period (1868-1912).
Composition and Production:
These coins were primarily made from copper. Production of 2 sen coins began in 1873, following the adoption of the new yen currency system in 1871.
Design:
The coin features a dragon on one side, often within a beaded circle, and the value within a wreath on the reverse. Early versions (1873-1877) are notable for their "square scales" dragon design, differing from later coins with "V" shaped scales.
Historical Significance:
The dragon motif on these coins reflects both Japanese mythological symbolism and the imperial themes of the Meiji era.
Collectibility:
2 sen coins were discontinued in 1884 and demonetized in the mid-20th century, but they are now sought after by collectors, with their value depending on the date and condition.
