Japan Meiji 1¥ gold coin M4(1871) [solved]

No problem identifying this coin as Japan Meiji 1¥ gold coin M4(1871), 

but would like more information on its plastic holder/container.

Was this done by Ministry of Japan?

Or a Japanese grading service?

Any thoughts?

I know this type of plastic would not have been used back then!!

Did you ask the Ebay seller? Maybe they know. 

If I remember correctly coins with holder that look like this were from sales from remaining coins of the Bank of Japan.

@idolenz: then i can conclude, a 1yen coin in this capsule was not in circulation, it has unc conditon?

No, it doesn't have to be unc. On the above picture it says: average quality.

I could use the info of this topic to buy one.

update: gold standard of yen was reduced 1897, most probably a central bank would keep the older coins years before that change.

“remaining” coins were sold in a representative package like this

certificate, which i cannot read:

Is there any information, when these packages were sold?

The text is about that the gold coins were confiscated by the Americans after the WW and later returned after a treaty as well as the change of the old and new gold coins, the new ones having half the gold content of the old ones.

The last sentence states that the new coins could be essentially still be used as money until 1988 so I would guess late 80s early 90s.

many thanks for translation/explanation.

I like the connection between coins and history, this small and beautyful coin went around the world: Japan- US- Japan- ?- sweden- germany.

Google translated

Immediately after World War II, this gold coin, along with other precious metals, was confiscated by the General Headquarters of the Allied Forces (GEQ), and then returned to the Japanese government with the conclusion of the San Francisco Peace Treaty in 1951. It's something.

G History of modern gold coins)

Modern gold coins include old gold coins and new gold coins. The Meiji government changed the currency unit from the previous ``ryo'' to the ``yen'' by promulgating the ``New Currency Ordinance'' regarding the currency system in 1899 (the former 1 ryo was made equivalent to 1 yen). In addition to 20 yen (formerly 20 yen), 10 yen (10 yen per day) and 5 yen (5 yen per day). 2 yen (formerly 2 yen) and 1 yen (formerly 1 yen) were issued. These are now called old gold coins. The design is ``Noh'' symbolizing the Emperor on the front, the Japanese emblem and paulownia crest on the back, a brocade flag with sun and moon on the left and right, and decorations of chrysanthemum and paulownia branches.

It was created using a sophisticated method. After that, in 1899, the ``Money Act'' was enacted, and new coins of 20 yen (new 20 yen), 10 yen (new 10 yen), and 5 yen (new 5 yen) were issued, and the value of the yen relative to gold was sufficient. Since the old gold coin contained twice as much gold as the new gold coin, it was decided to circulate it at twice the value of the new gold coin. The back is a combination of ridged mirrors, and the front is a chrysanthemum crest, paulownia crest, chrysanthemum and paulownia branches, and a plaque.

These modern gold coins could be used effectively as money until 1988, but they are no longer usable as money.
