The obverse side features a dragon with an open mouth, while on the reverse there is a paulownia decoration with a sunburst in the center, and the chrysanthemum seal up on top. While dated 1870 (year 3), these first year ten sen coins were not released into circulation until the following year (1871). During this time, the coins along with twelve other denominations were adopted by the Meiji government in an act signed on June 27, 1871.A.

An amendment to the currency act (Daijo-kan Declaration No. 74) was adopted in March 1872 (year 5) which intended to increase the weight of the ten sen coin.

Production resumed under Emperor Taishō in 1912 and World War I broke out two years later. This event brought Japan a booming economy which required an increase of small denomination coins.

Ten sen copper nickel coins were eventually produced in large amounts which peaked in 1922 and 1923 (year 11 and 12). This was done to encourage the public to redeem old ten sen notes for coins, which lasted into the Shōwa era. No additional changes regarding ten sen coins were made during the remainder of Emperor Taishō's reign. Shōwa coinage (1927–1946) Copper nickel ten sen coins resumed production in 1927 (year 2 of Shōwa) and continued to be minted until 1932 (year 7).

The effect of the amendment is to alter the weight and composition of the coins of 10 sen and 5 sen denomination. The width of ten sen coins dropped slightly by 0.1mm to 22mm, and the weight was increased from 3.8 to 4 grams. Pure nickel was chosen as an alloy as an anti-counterfeiting measure because it was difficult to process with the technology of the time.http://pepper.cool.coocan.jp/round/10sen_nickel.htm 十銭ニッケル貨 Pepper's Square Japanese December 12, 2020 Another reason has to do with the Mukden Incident in 1931 (year 6), and subsequent Japanese invasion of Manchuria.

An aluminium bronze alloy consisting of 95% copper and 5% aluminium thus replaced ten sen nickel coins as nickel was needed for munitions. The only changes made to the coins other than their alloy was a new design and a smaller central hole.

Collecting The value of any given coin is determined by survivability rate and condition as collectors in general prefer uncleaned appealing coins. For this denomination, there are a few major varieties and multiple design changes which occurred during three different imperial eras. The first coins minted are Asahi Ryu or rising sun dragon coinage which only has one year (Meiji 3), but consists of two different varieties regarding scales on the dragons design. As with the other denominations, those with clear (deep) scales are worth more than obscure (shallow) ones.https://antique-coin.info/kaitori/error-10sen/#keni_toc_0 高価買取が期待できるエラー旭日竜10銭銀貨 Antique Coin Info Japanese January 4, 2020 December 15, 2020 Overall these first year of issuance coins are "reasonably priced" with average value in the several thousands of yen. The second design was much longer lasting in comparison as it was featured on coins from 1873 to 1906 (year 6 to 39). Another similarity with other denominations occurs here with the character "明" in Meiji's name on the obverse. Coins dated 1873 and 1875 (year 6 and 8) either have both features separated as the first variety, or have a line connecting both the left and right features as the second variety.https://antique-coin.info/kaitori/10sen-kachi/#keni_toc_1 竜十銭銀貨 Antique Coin Info Japanese August 25, 2018 December 15, 2020 Those with the second "connected" variety are worth more than their counterparts. With a mintage of just 77 coins, ten sen coins dated 1880 (year 13) are not even listed by some Japanese price guides.https://kosen-kantei.jp/varity/10-sen-coin/ 【保存版】10銭硬貨の買取価値はいくら？平均価格＆査定相場《全10種類》 Kosen Kantei 5 November 2019 Japanese December 15, 2020https://kosenkaitori.info/koka/10sen/ 10銭硬貨の買取価格とおすすめ買取業者について Kosen Kaitori Japanese December 15, 2020 They are estimated to be worth in the low millions of yen. An overall assessment on coins made from 1873 to 1906 has common dates valued at 1000 yen in average condition. Rare dates include; 1874, 1901, and 1902 (Meiji 7, 34 and 35) and are potentially worth more than 10,000 yen in average condition. The third design is used on the last of the ten sen silver coins dated from 1907 to 1917. As there are a lot of surviving coins for these dates, they are generally priced lower except for those in high grades. Copper-nickel coins debuted under Emperor Taishō in 1920 (year 9 of Taishō) as the price of silver bullion had risen too high. The most valuable of these coins under Taishō were made during this first year.https://antique-coin.info/kaitori/t9-10sen/ 10銭白銅貨(大正9年〜15年)の価値と買取価格 Antique Coin Info 26 March 2017 Japanese December 16, 2020 Production amounts increased afterwards for the remainder of Taishō's reign to redeem 10 sen notes, which left plenty of surviving coins for collectors to obtain. These amounts in general drop with coins produced from 1927 to 1932 (year 2–7) of the Shōwa era. When ten sen coins were switched to nickel, a lot of these may have been redeemed at the bank. Coins of this period can still be collected "relatively easily" as enough surviving coins remain. An anomaly occurs with coins dated 1929 (year 4), when compared to the much lower mintage 1931 (year 6) date in terms of value. As the number of existing coins in good condition for 1931 outnumbers those from 1929 (year 4), the latter date is valued more in higher grades.https://antique-coin.info/kaitori/s4-10sen/#keni_toc_0 昭和4年の特年10銭硬貨の価値と買取相場 Antique Coin Info 28 December 2017 Japanese December 16, 2020 As a caveat, there were a "considerable" amount of contemporary counterfeit coins sold at the time as the value of the metal was low relative to the coin's face value. There is nothing "particularly rare" about the nickel series issued from 1933 to 1937 (year 8 to 12) other than proof strikes which are valued in the hundreds of thousands of yen.https://antique-coin.info/kaitori/s8-10sen/#keni_toc_0 昭和8年〜昭和15年の10銭硬貨の価値 Antique Coin Info February 2018 Japanese December 16, 2020 Nickel ten sen coins are usually found in better conditions as the alloy is a stable resistant metal. Aluminum bronze coins made from 1938 to 1940 (Year 13 to 15) were released for such a short time that many of them were held on to. The aluminum coins that replaced these were produced in even larger amounts in three different varieties. Scarce 1943 (year 18) dated coins weighing 1.2 grams are the most valuable among these and carry a premium.https://antique-coin.info/kaitori/s18-10sen/#keni_toc_0 昭和の菊10銭アルミ貨の価値と買取相場 Antique Coin Info 29 December 2017 Japanese December 16, 2020 Post-war inflation made coins produced from 1944 to 1946 (year 19 to 21) essentially worthless which gave the public no incentive to cash them in. These coins have low value as an abundance of survivors in all conditions can easily be obtained by collectors.
