Tolong jelaskan mengenai Coins dari Yén Jepang dalam bahasa sunda

The 5-yen and 50-yen coins are holed.  The date is on the reverse of all coins, and, in most cases, the name 日本国, Nihonkoku (Japan) and the value in kanji is on the obverse, except for the 5-yen where Nihonkoku is on the reverse.

The first 1-yen coin (excluding éarly silver coins) was a brass coin introduced in 1948, and discontinued in 1950, the first 5-yen coin (excluding éarly gold coins) in 1948, and originally had no hole.  The first 10-yen was introduced in 1951, the first 50-yen in 1955 (with no hole), the first 100-yen in 1957 (originally made out of silver).  The 500-yen coin was introduced in 1982  .

500 yén coins are probably the highest valued coins to be used regularly in the world (with rates in the neighborhood of US$4.77, €3.59, and £2.49).  The United States' largest-valued commonly-used coin (25¢) is worth around 26 yen; the Eurozone's largest (€2) is worth ¥279, and the United Kingdom's largest (£2) is worth ¥402 (as of March 2005).  The Swiss 5-franc coin is currently (as of May 2006) worth about ¥457. The highest valued bill, the 10,000 yén bill, is worth just a little bit less than the U.S. $100 bill, the highest denomination of currently circulating U.S. currency.

On various occasions, commemorative coins are minted using gold and silver with various face values, up to 100,000 yén  .  Even though they can be used, they are tréated as collectibles.
