There is an another mintmark that looks like 千, the イ mintmark.To distinguish them, use the 通 character on obverse:
The 千 mintmark ones tend to have マ as head of 通, while the イ mintmark ones tend to have コ as head of 通.
Interesting fact
One interesting fact about the 4 Mon "Kan'eitsūhō" coin from Japan is that it was made of iron, which was a unusual choice for coinage at the time, as most coins were made of precious metals like gold, silver, or copper. The use of iron in coinage was seen as a way to reduce the cost of production and make currency more accessible to the general population. This coin was also unique in that it featured a reverse design of 千 "Sen" (meaning "thousand") and was part of a series of coins introduced during the Meiji Restoration, a period of rapid modernization and reform in Japan.
