US Trade Dollars
This coin was issued for circulation in the Orient to compete with dollar-sized coins of other countries. Many pieces that circulated in the Orient were counterstamped with Oriental characters, known as chop marks. They were legal tender in the United States, but when silver prices declined, Congress repealed the provision and authorized the Treasury to limit coinage to export demand. In 1887, the Treasury reddemed all trade dollars that were no mutilated. The law authorizing trade dollars was repealed in Febrary 1887. Modifications to the trade dollar design are distinguished in four ways blah blah blah
1878 was made about 900, at lest $1200
1878CC was made about 97,000, worth any where from $450 to $20,000
1878S was made about 4,162,000, worth any where from $110 to $1,600
美国贸易银币 用于当时的国际贸易 国内俗称“拿花”
假的非常非常之多，如果是真的也看品相的，普通无伤品相得再400以上的。
1878年的拿花坐人属于非常好年份
很贵的
具体价值得看品相和真假
上图看看
