Saya mau tau Jepun dari Dolar perdagangan. Jelaskan dalam bahasa melayu

The Japanese Trade Dollar was a dollar coin, issued from 1875 to 1877. It was minted of 27.22 grams of silver with a fineness of 900 (90 %). The Yen coin had 26.96 grams of silver at that time.

2,736,000 Japanese coins were minted, the vast majority in 1876-77.  Because of their high bullion value they were withdrawn from use and the majority were counterstamped with the character "gin" (Japanese for "silver").  The Osaka mint placed the mark on the left side of the reverse, the Tokyo mint on the right.  The coins were then released for use outside Japan.
