Round-shaped coins are handled easier than square-shaped coins. They are more resistant than other-shaped coins against erosion.

(1) identify the specific coin easily (distinguish the specific coin from others).

25. Japan Mint & Historical Spots?
Sempukan
Having been designated an important cultural property by the Ministry of Education in 1956, this building named "Sempukan" is known to be one of the oldest Western-style buildings existing in Japan. The Sempukan was built in 1870 by Thomas Walter, a British architect. It was originally used as a reception hall by Japan Mint, today, however, it is the property of the City of Osaka.
Yoriki Yakutaku Mon (an entrance to the Edo Period officer-of-the-law's residence)
The whole neighborhood presently called Temma, now the seat of Japan Mint, was in the Edo period (1615 to 1868) the official residence of those days' Temma Yoriki (law enforcement officials). The entrance located in front of the Mint Club House is one of the gates. (It is said to have belonged to Tohnai Nakajima, a Yoriki).
The old site of "Senshindo" (designated a prominent historical place by the Osaka City Government)
Here Heihachiro Ohshio, a former Temma Yoriki resided, opened a private school named "Senshindo" and taught various learning. Because of the distressing circumstances of the common people during the Tempo 8 (1837) famine, he started an insurrection known as "Tempo-no-ran" (The Tempo Revolt).
Gaslights
The pair of gaslights located just inside the old Front Gate are the oldest in Japan still remaining in good condition today.
