Meiji
The following are circulation figures for the two yen coin, all of which were minted between the 3rd, and 25th year of Meiji's reign.
The dates all begin with the Japanese symbol 明治 (Meiji), followed by the year of his reign the coin was minted.
Each coin is read clockwise from right to left, so in the example used below "九" would read as "year 9" or 1876.
It is unknown if genuine coins dated 1874 even exist as they remain "unverified".
Two yen coins were struck in 1892,  but none were released for circulation.

"Year" ← "Number representing year of reign" ← "Emperors name" (Ex: 年 ← 九 ← 治明)
