06.06.1921
12.10.1921
26.12.1921
30.01.1923
16.02.1929
So as of today the proved time horizon for this mark is 1915-1929.
That's exactly why this mark could not be used by the Hiroshima branch of the Japanese mint (popular "legend" says that Hi /ヒ/ stands for Hiroshima).
The decision to build
造幣局 - Mint
広島支局 - Hiroshima Branch
was made only in 1942.
The new branch was planned to be used for the minting of Japanese puppet states coins.
But first coins were minted only in February 1945 (five months before the atomic bombing).
Hiroshima branch nowadays.
