Overview

A small copper-nickel coin with a central hole, featuring a chrysanthemum throne on the front and Paulownia flowers on the back.

Historical significance

This coin dates to the final year of the Taisho era (1912-1926). It represents the transitional period of Japanese coinage before the Showa era began later that same year.

Obverse (front)

Central hole surrounded by stylized Paulownia flowers (Mon) below, value in Kanji characters (10 Sen) above, divided by the Imperial Chrysanthemum Seal.

Reverse (back)

Central hole surrounded by a Qinghai wave (Seigaiha) pattern; top legend reads 'Great Japan', bottom legend reads 'Taisho Year 15'.

Estimated value

$1-$5 circulated, $15-$40 in Mint State

What drives this coin's value

Condition (grade) and year of issue. High-grade specimens with original luster are much more valuable.

Grade assessment

Very Fine to Extremely Fine (visible wear on the waves and the chrysanthemum petals).

Mintage & rarity

Approx. 34,700,000; common although the final year (Taisho 15) is popular with collectors.

Authenticity & counterfeit red flags

Check for magnetic properties (should be non-magnetic), verify weight and diameter, and look for sharp, non-mushy Kanji lettering.

Notable varieties & errors

Minor die rotations or planchet flaws.

Similar coins

5 Sen coins of the same era, which are smaller. Showa era 10 Sen coins look similar but have different dates.

Care & preservation

Store in a PVC-free flip or capsule. Do not clean or polish as it destroys numismatic value. Handle only by the edges.
