a little confusing

"1ryō(1 gold coin) = silver coin 50 monme = copper coin 4 kanmon(貫文)"
1609、the Tokugawa Shogunate defined exchange rates in this way.

Monme was unit of weight.
(1 monme was about 3,75g )

Copper coin 4 kanmon was about 15000g.
15000 ÷ 4 = 3750
Therefore 1 kanmon is 1000 monme.

Incidentally 1 ryō is 4,76 monme.(about 17,85g)

"gold coin 17,85g = silver coin 187,5g = copper coin 15000g"
In short、the Tokugawa Shogunate defined exchange rates in this way.

・・・・・・・・・

By the way、there was one problem.

Copper coin、it was the smallest unit of the money from old time.
Its 1 piece called 1 mon(文).

"1000 mon is 1 kanmon."
It was defined like this.
In other words、1 mon was 1 monme.

And money that is used primarily was this copper coin.

But it was various copper coins of the previous era.
The difference in casting standard、coins worn down.
Its quality was not constant、but people had to accept it.

※I don't know now whether the coin had been purely cast in copper.
I feel like that mixed something like glue. ※

Various negative effects naturally occured by it.
It was a factor that inhibits against the development of the economy.

Tokugawa was required to improve this problem as soon as possible.
In 1636、they coined a homogeneous copper coin.

It called "Kan'ei tsūhō".(寛永通宝)
　
・・・・・・・・・

And although this is a little confusing.
　
"1 kanmon is 1000 mon."
This called Chō sen-hō.（丁銭法）
※法(hō) in this case is probably"way・method".

"1 kanmon is 970 mon or 960 mon."　
And how to count like this were also present.
This called Seihyaku-hō.（省陌法）

"1 kanmon is 960 mon".
It seems that Tokugawa has adopted this method
(But same as before、weight of 1 mon was 1 monme.)

960 × 4 × 3,75 ＝ 14400

"gold coin 17,85g = silver coin 187,5g = copper coin 14400g"
In short、the Tokugawa Shogunate defined exchange rates in this way.

・・・・・・・・・

Silver coin 1000 monme called 1 kan・me.(貫目)
Copper coin 1000 monme called 1 kan・mon.(貫文)

In short、in this case kan(貫) seems a unit of thousand.（千）

And although this is a little confusing(as me・lol).

Brass、iron.
Material of copper coin was not only copper.

The late 19th century、when the Meiji Restoration.
About 70% of the coins in circulation、it was 1 mon of copper coin of iron.

Tokugawa coinage

the price

There was a content of the coins of course.
1ryō(gold coin) = silver coin 50 monme = copper coin 3840 mon

1 ryō is 4,76 monme.
And the gold content is 86,79%.

4,76×3,75×0,8679＝15,492015
　
Silver content of silver coin was 80%.
50×3,75×0,8＝150g　

Copper was probably copper.(brass、iron)

Gold 15,492015g = Silver 150g = Copper 14400g

According to the site of Tokyo commodity exchange.
(as of Jun 17, 2013 19:15)
　
Gold 1g was ¥ 4,245.
Silver 1g was ¥ 66,2.

4245×15,492015＝65763,603675
66,2×150＝9930

Of course ¥65764 is not ¥9930.

※And、I was writing like this.
Please read loosely、"He writes like this"(lol).

・・・・・・・・・

"1 ryō is price of 1 koku(石)."　
First、the Tokugawa Shogunate defined in this way.

1 koku was rice about 180 liter.
180 liter≒180 kg.　
Currently、rice 10 kg is about ¥4,000.　
　
4000 × 18 ＝ 72000
※4000 × 15 ＝ 60000

1 ryō : 1 koku
Gold : Rice
¥65764 : ¥72000
(¥65764 is the current price of gold、which is included in 1 ryō・¥72000)

※¥65764 : ¥60000
60000 × 0,8679＝52074

2010 and 1600.
Balance of the price of rice and gold.
It does not change so much.

Probably value of gold was much the same now.
And value of silver was very higher than now.

65764 ÷ 9930 ＝ 6,6227593152
In 1600 at that time、silver was the price of about 6,6 times than now.

※The conclusion is、the population of Japan has also multiplied several times、that the progress of current rice cultivation technology is great(lol).※

・・・・・・・・・

Gold 15,492015g = Silver 150g (at early 17th century)

150 ÷ 15,492015 ＝ 9,6824073563

Gold 1 = Silver 9,6824073563 (at early 17th century)

Gold 1g ¥ 4,245. (Jun 17, 2013 19:15)
Silver 1g ¥ 66,2.(Jun 17, 2013 19:15)

4,245 ÷ 66,2 ＝ 64,1238670694

Gold 1 = Silver 64,1238670694 (Jun 17, 2013 19:15)
　
Early 17th century、the price of silver of Japan was clearly higher.
I understood so.

"At that time、price of silver of Japan was cheaper than neighboring countries.
Therefore many silver flowed out to overseas as export items."
However、it was written so in the electronic dictionary.
Of course I had strange feeling to it.　
　
I was examined this at ”money”（貨幣/kahei）.　
Next、I was examined this at ”price comparison of gold and silver”.
(金銀比価/kingin－hika)　

※If Japan at that time was one of the world's leading producers of silver、this is no wonder at all、and of course.

Gold 1g ¥ 4,245. (Jun 17, 2013 19:15)
Silver 1g ¥ 66,2.(Jun 17, 2013 19:15)※
